Need suggestions for documenting the GTK file chooser

Note that if you decide to use an InBox or Media GTK File Chooser, you can set a button on that chooser to shortcut any saved filepaths:

  • Bookmarks: are created by the user, by dragging folders from the right pane to the left pane, or by using the “Add”. Bookmarks can be renamed and deleted by the user.

  • Shortcuts: can be provided by the application. For example, a Paint program may want to add a shortcut for a Clipart folder. Shortcuts cannot be modified by the user.

  • Volumes: are provided by the underlying filesystem abstraction. They are the “roots” of the filesystem.
