My Three Suggestions, near the bottom, are:
1. Support and interact with KDE KIO-slaves
2. Create/support a common backend for File Open/Save type dialogs with OpenDesktop and KDE, so that apps from either DE feel native
3. File picker dialogs (File Open/Save) should obey single-click browsing and opening if other parts of a Gnome app are configured that way. Double-clicking in the picker is confusing and difficult if the rest of the desktop is single click.This last one has been a bug for almost a decade now...
What are you're requests for GNOME? Are you a GNOME user?
