Support byobu like gnome-terminal

When I set byobu (a terminal "window manager") as a command to execute when guake starts and I then type "exit", instead of the guake window dissappearing (as gnome-terminal does), buobu exits and guake window stays (when I type exit again, it goes away too). When I then press F12 to invoke guake again, byobu is no longer running and i have to realunch it.

What I would like is that guake would track the command that it spawns (byobu) and it would interpret the command exit as a command for the window to dissappear. Ideally, the command (byobu) would be then launched again on another invocation of that command. This would allow the possibility to always have byobu running when guake is running (and this would actually make me use guake, wihch I otherwise like very much, only I like byobu better and I am too used to typing exit to close down/make dissappear a terminal window).
