I think that's fairly easy to implement if you just have submenus "Desktop Properties" "Change Desktop Background" "Change Resolution" "Change Theme" "Change Window Behaviour" "Change Font"Please don't.
I already didn't find this an attractive solution
A nicer solution I think is to have just one menu item which fires up a dialog with 5 tabs, which contain the 5 previously mentioned items.That's like 1:1 copy of windoze dialog :). I don't really see reason to do that this way, decent shell with easy access to all capplets would be much better (and from what I've seen in XD2 screenshots, I like their MacOSX-like control-center shell, I'd vote for stealing it for upstream GNOME :)
Are you referring to the screenshot called "Customize Your Workspace" on http://www.novell.com/products/desktop/screenshots.html That's indeed a very nice looking solution. Vote +1 Jaap
