I <3 my Xfce.
Hm, the move to Gtk3 is sad news… It means crappy themes and broken scrollbars .
Also Thunar 1.4 is better than 1.6. The new shortcuts pane wastes vertical space and the reload button is in the wrong place (à la Firefox).
I must admit many GTK3 applications are looking a bit odd for me at the moment when using other non-Gnome DEs.
