I think USP looks great, but I really prefer the three button option of Ubuntu's default panel. Would it be possible to have USP act as three (possibly more) menu buttons?
I like the App menu and the Places menu, thought I think that the System menu could be split up into a System menu(for Admin stuff) and a Customize menu for theming, mouse settings, keyboard stuff, etc.
The reason I prefer the multi-button solution is that the one menu for everything solution is just too clutered, in my opinion. After beginning to use Ubuntu after years away from Linux, I find that I really dislike the Windows Start menu because of the kitchen sink approach; I know what I want to do and everything else is just a distraction.
The look and feel of USP is great and I'd like to use it. So I figured what the hell and ask if it is possible to go multibutton with it.
