GNOME Bugzilla – Bug 698365
Recently Used view should sort by last used time, not modification time
Last modified: 2015-07-08 11:44:01 UTC
The Recently Used view in GtkFileChooser has a Modified column and sorts files by modification time. Instead, it should display and sort by the time a file was last used. See bug 686137 for the same issue in Nautilus's Recent view. See also bug 679334 (about making GtkFileChooser and Nautilus consistent in general).
This has been fixed: https://git.gnome.org/browse/gtk+/commit/?id=412e33da168a07e903aa13386bd602fa3379ccc0
