I don't get it.
Ratpoision seems TOO minimalistic. I do everything you do, except with a gnome/sawfish combination. I set up virtual desktops with four terminals side-by-side so I can see several processes going at once, and I still have room to fit in everybuddy and xmms w/ playlist. Having a full screen for something like everybuddy seems rather absurd to me. The only thing I want to run fullscreen is galeon, which I do. I have windowmaker style key bindings to switch between virtual desktops, plus alt+tab bound so I can pretty do whatever I want fast enough. Ratpoison seems less powerful and more like a burden to me.
