I particularly liked the way Guake looked by default in 2.3. There was partial transparency, but it was transparent all the way through to my wallpaper, rather than showing any applications open. That is to say, I am typing this into firefox now, in full screen mode. If I were to press F12 and have Guake drop down, the background to the Guake window would be my wallpaper, not firefox.
I never managed to get Guake to behave this way in non-UE distros, and one disappointment to me in Ultimate Edition 2.4 is that Yahuake does not behave this way at all either. I've tried to install Guake but I think perhaps it has been discontinued and replaced by Yahuake.
Does anyone know if it is actually possible to get Yahuake to appear this way? I know it isn't really important in the larger scheme of things, but I really did like it
