[xmonad] New ideas [was: Trying to code jump-or-execute]

Hi I don't know if this is already possible or not, I am a relatively new user (and new to haskell). I would like to be able to hide a window. I tend to use workspace one for the internet and anything else that I shouldn't be doing at work, and it would be nice to be able to hide firefox behind the terminal and emacs so that is doesn't clutter the screen but still keep the current layout David Collins
