works great for xfce Rated 5 out of 5 stars

I thought dispite the warning, that I'd give it a try in xfce... and it works great! I have to wonder if the developer simply wants to promote the use of gnome3... Dear Developer.... I love gnome, I've been a hard-core gnome supporter since the project began, however my system is too old and week to support gnome3, and I need some of the modern fetures, so I don't have a choise but to use a ligher weight DE... hence xfce... please don't go trying to lock it out for people like me.
