+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+.SH DESCRIPTION
+.B gedit
+is an easy-to-use and general-purpose text editor. Its development started
+in 1998, at the beginnings of the GNOME project, with a good integration with
+that desktop environment.
+
+You can use it to write simple notes and documents, or you can enable more
+advanced features that are useful for software development.
+
+.LP
+.SH OPTIONS

+starts. If this is not specified,
+.B gedit
+will load a blank file with an "Unsaved Document" label. Multiple files can be loaded if they are
+separated by spaces.
+.B gedit
+also supports handling of remote files. For example, you can pass the location
+of a webpage to
+.B gedit
+, like "http://www.gnome.org", or load a file from a FTP server,
+like "ftp://ftp.gnome.org/robots.txt".
+.TP
+\fB-\fR
+.B gedit will read from stdin
+.TP

+gedit installation by building the source code
+==============================================
+
+Recommendation to install in a separate prefix
+----------------------------------------------
+
+Once you have built gedit from source, you cannot run the application from its
+build directory: you need to install it with `ninja install`. For this reason it
+is highly recommended that you install in a separate prefix instead of
+overwriting your system binaries.
+
+Note however that when running gedit from a custom prefix you will need to set
+many environment variables accordingly, for instance `PATH` and `XDG_DATA_DIRS`.
+
+There exists several tools that GNOME developers use to take care of all of
+this. See the _Tools_ section below.
+
+Installation of the dependencies
+--------------------------------
+
+You need to have all gedit dependencies installed, with recent enough versions.
+If a dependency is missing or is too old, the build configuration fails (you can
+try to run the build configuration command for gedit until it succeeds, see the
+procedure below).
+
+You can install the dependencies by installing packages provided by your
+operating system, for example on Fedora:
+```
+# dnf builddep gedit
+```
+
+But if your version of gedit provided by the OS differs too much from the
+version of gedit you want to build from source, you'll need to install the new
+dependencies from source too, and it can become a complicated task if you do it
+manually.
+
+Also, during gedit development, gedit may depend on a not-yet-released
+development version of a dependency. So certain dependencies may need to be
+installed from Git.
+
+That's why if you have difficulties installing recent enough versions of the
+dependencies, it is usually easier to use one of the tools explained in the next
+section.
+
+Tools
+-----
+
+There are several tools available that take care of the following:
+- Install in a separate prefix.
+- Build or install dependencies.
+- Plus, for some tools: run in a container/sandbox.
+
+GNOME developers usually use one of these tools:
+- [Toolbx](https://containertoolbx.org/) (probably the easiest)
+- Or [Flatpak](https://flatpak.org/)
+- Or [JHBuild](https://gitlab.gnome.org/GNOME/jhbuild)
+
+General tips for gedit:
+- At the time of writing, no need to build GLib or GTK from source, taking their
+  latest stable versions are sufficient.
+
+JHBuild tips:
+- Try `ignore_suggests = True` in your jhbuildrc to have fewer dependencies to
+  build (see the difference with "jhbuild list gedit"). Another solution is to
+  put some modules in the skip variable in jhbuildrc.
+- Note that the moduleset for gedit may be out-of-date.
+
+Building the gedit module manually
+----------------------------------
+
+If you use one of the above tools, you don't need all the explanations in this
+section. But it can be instructive.
+
+gedit uses the [Meson](https://mesonbuild.com/) build system.
+
+Once the dependencies are installed, here are simple procedures to finally build
+the gedit module from source.
+
+### Installation onto the system
+
+**Warning**: this procedure doesn't install in a separate prefix, so it may
+overwrite your system binaries.
+
+```
+$ cd build/
+$ meson setup                # Build configuration
+$ ninja                      # Build
+[ Become root if necessary ]
+$ ninja install              # Installation
+```
+
+### Installation in a separate prefix
+
+Just change the above `meson setup` command by:
+```
+$ meson setup --prefix /an/other/path
+```

+Common gedit bugs
+=================
+
+This page documents common bugs in gedit. If you find your problem in this page,
+_please do not report a new bug for it_.
+
+Problem with very long lines
+----------------------------
+
+Very long lines (e.g. a wrapped line that takes the whole screen) are not well
+supported by gedit, there can be performance problems or freezes.
+
+[GitLab issue](https://gitlab.gnome.org/World/gedit/gedit/-/issues/513).
+
+Problem with very large files
+-----------------------------
+
+Large files are not well supported, gedit should ask for confirmation when
+opening such files, providing a solution.
+
+[GitLab issue](https://gitlab.gnome.org/World/gedit/gedit/-/issues/11).
+
+Hyphen/dash inserted for text wrapping
+--------------------------------------
+
+It should be disabled in a text editor like gedit, the hyphen is not part of
+the content.
+
+[GitLab issue](https://gitlab.gnome.org/World/gedit/gedit/-/issues/365).
+
+Recently fixed

+gedit development - getting started
+===================================
+
+The following explanations can be improved over time, if you see something
+missing, a feedback is welcome.
+
+Programming languages and paradigms
+-----------------------------------
+
+gedit is mostly written in C, with some plugins in Python. The
+[Meson](https://mesonbuild.com/) build system is used.
+
+The code is object-oriented and event-driven. In C, it's thanks to the use of
+the GObject library (see next section). If you open some `*.c` or `*.h` files,
+you may be frightened but – don't panic – it's just some C/GObject boilerplate
+code, and that boilerplate can be generated by a tool. So once you've learned
+GObject, you will no longer be afraid ;-)
+
+Libraries used
+--------------
+
+As every GNOME application, gedit uses the GLib, GObject and GTK libraries. To
+modify the gedit source code, you should be familiar with those libraries. See
+the [GTK website](https://www.gtk.org/) and
+[The GLib/GTK Development Platform – A Getting Started Guide](https://github.com/gdev-technology/glib-gtk-learning).
+
+The main "text area" in gedit is a GtkTextView widget. This widget is part of
+GTK. You can learn it with the
+[GtkTextView tutorial](http://www.bravegnu.org/gtktext/). The tutorial is a bit
+old but the GtkTextView API has not changed a lot. (By the way, contributing to
+update the tutorial would be a useful task!).
+
+GtkTextView provides the basis, and is extended by other libraries to add more
+features. See [Gedit Technology](https://gedit-technology.github.io/).
+
+For its plugin system, gedit uses
+[libpeas](https://wiki.gnome.org/Projects/Libpeas).
+
+Plugins may have other dependencies, for example the spell-checking plugin uses
+[gspell](https://gitlab.gnome.org/GNOME/gspell).
+
+gedit architecture
+------------------
+
+The [gedit git repository](https://gitlab.gnome.org/World/gedit/gedit) contains:
+- The "gedit core" in the `gedit/` directory.
+- The default plugins in `plugins/`.
+
+There is also the
+[gedit-plugins git repository](https://gitlab.gnome.org/World/gedit/gedit-plugins)
+for additional official plugins.
+
+The gedit core provides:
+- A basic text editor.
+- The integration of libpeas, with an API for plugins.
+
+There is a class diagram of gedit core in the file
+[class-diagram.dia](class-diagram.dia) (but it may be outdated, see the Git log
+for that file).
+
+Build/Installation
+------------------
+
+See the file [build.md](build.md).
+
+Suggestions
+-----------
+
+A good way to learn a lot of things is to write a new plugin (it can be a
+third-party plugin at first).
+
+Improving the API reference of the gedit core would be useful, because some
+parts lack proper documentation.
+
+A potentially easy task is to fix compilation warnings, for example when a
+deprecated function is used. If you encounter a runtime warning or critical
+message, it is also a good idea to fix it.
+
+Note that gedit is an old piece of software. Some parts are legacy code and
+would benefit from some refactoring.

+How to write a gedit plugin
+===========================
+
+The [gedit-development-getting-started.md](gedit-development-getting-started.md)
+documentation is a good start.
+
+Programming language for a gedit plugin
+---------------------------------------
+
+The preferred language is the C language, that way the code can be easily
+refactored to be included in a library.
+
+Rust, C++ and Vala plugins are possible too since they are equivalent to C.
+
+Python plugins are possible too.
+
+### What if I prefer to write in Ruby/JS/Scheme/Perl/C#/modula-2/Oz/whatever…
+
+While GObject allows you to use many other languages, using more than one
+interpreter in the same process is not possible, not only because of bloat and
+performance, but also because different interpreted languages cannot manage
+garbage collections of GObjects at the same time: see
+[this email](https://mail.gnome.org/archives/desktop-devel-list/2010-August/msg00036.html).
+
+The gedit developers have chosen Python as the interpreted language.
+
+API reference
+-------------
+
+Build gedit with `-D gtk_doc=true`, you can then browse the API reference in the
+[Devhelp](https://wiki.gnome.org/Apps/Devhelp) application.
+
+To know how to write a plugin, refer to the
+[libpeas](https://wiki.gnome.org/Projects/Libpeas) documentation as well.
+
+More documentation and tips
+---------------------------
+
+More documentation, for example a tutorial, would be useful. In the meantime,
+the recommended thing to do is to see how core gedit plugins are implemented.
+
+### Unofficial documentation and tutorials (may be outdated)
+
+- [Writing plugins in Python](https://wiki.gnome.org/Apps/Gedit/PythonPluginHowTo) (a little outdated)
+- [Writing plugins in Vala](https://wiki.gnome.org/Projects/Vala/Gedit3PluginSample) (maybe outdated)

+gedit roadmap
+=============
+
+This page contains the plans for major code changes we hope to get done in the
+future.
+
+Take care and fix the common bugs
+---------------------------------
+
+Status: **in progress**
+
+See the list in the [common-bugs.md](common-bugs.md) file.
+
+Continue to make the gedit source code more re-usable
+-----------------------------------------------------
+
+Status: **in progress** (this is an ongoing effort)
+
+Develop and use the [Gedit Technology](https://gedit-technology.github.io/) set
+of libraries.
+
+Rework the search & replace UI
+------------------------------
+
+Status: **todo**
+
+Have an horizontal bar, to not occlude the text.
+
+Be able to quit the application with all documents saved, and restored on next start
+------------------------------------------------------------------------------------
+
+Status: **todo**
+
+Even for unsaved and untitled files, be able to quit gedit, restart it later and
+come back to the previous state with all tabs restored.
+
+Improve the workflow for printing to paper
+------------------------------------------
+
+Status: **todo**
+
+Show first a preview of the file to print and do the configuration from there.
+
+Use native file chooser dialog windows (GtkFileChooserNative)
+-------------------------------------------------------------
+
+Status: **todo**
+
+To have the native file chooser on MS Windows, and use the Flatpak portal.
+
+This task requires to rework the file loading and saving code. To have a
+different - but still user-friendly - way to choose the character encoding and
+line ending type.
+
+Avoid the need for gedit forks
+------------------------------
+
+Status: **todo**
+
+There are several forks of gedit available: [Pluma](https://github.com/mate-desktop/pluma)
+(from the MATE desktop environment) and [xed](https://github.com/linuxmint/xed)
+(from the Linux Mint distribution). xed is a fork of Pluma, and Pluma is a fork
+of gedit.
+
+The goal is to make gedit suitable for MATE and Linux Mint. This can be
+implemented by adding a “gedit-classic” configuration option. Or implement it
+similarly to LibreOffice, to give the user a choice between several UI
+paradigms.

+  <description xml:lang="en">
+gedit is an easy-to-use and general-purpose text editor. Its development started
+in 1998, at the beginnings of the GNOME project, with a good integration with
+that desktop environment.
+
+You can use it to write simple notes and documents, or you can enable more
+advanced features that are useful for software development.
