+// To do:
+// - Resize or show + hide the Time and Comment axes, possibly via one of
+//   the following:
+//   - Split the time, diagram, and comment sections into three separate
+//     widgets inside a QSplitter. This would resemble the GTK+ UI, but we'd
+//     have to coordinate between the three and we'd lose time and comment
+//     values in PDF and PNG exports.
+//   - Add separate controls for the width and/or visibility of the Time and
+//     Comment columns.
+//   - Fake a splitter widget by catching mouse events in the plot area.
+//     Drawing a QCPItemLine or QCPItemPixmap over each Y axis might make
+//     this easier.
+// - For general flows, let the user show columns other than COL_INFO.
+// - Add UTF8 to text dump
+// - Save to XMI? https://www.spinellis.gr/umlgraph/
+// - Time: abs vs delta
+// - Hide nodes
+// - Clickable time + comments?
+// - Incorporate packet comments?
+// - Change line_style to seq_type (i.e. draw ACKs dashed)
+// - Create WSGraph subclasses with common behavior.
+// - Help button and text
