 * - if no file operations are running, and one passes the two seconds
 *   timeout, a window is displayed with the progress
 * - if the window is closed, we show a resident notification, depending on
 *   the capabilities of the notification daemon running in the session
 * - if some file operations are running, and another one passes the two seconds
 *   timeout, and the window is showing, we add it to the window directly
 * - in the same case, but when the window is not showing, we update the resident
 *   notification, changing its message
 * - when one file operation finishes, if it's not the last one, we only update the
 *   resident notification's message
 * - in the same case, if it's the last one, we close the resident notification,
 *   and trigger a transient one
 * - in the same case, but the window was showing, we just hide the window
