In my dual monitor set up, I generally use my (larger) left hand monitor for working on. I'll have a browser workspace, a text editor workspace, and email workspace and so on. However, the smaller right hand monitor is reserved for "sticky" things like my IRC window, and my music player.
Currently I achieve this by manually setting "Always on visible workspace" for all the windows I place on the right hand workspace, but I'd like to know if there is a way to set it automatically for ones I place there, or if that is the kind of thing that is in the realm of a more wacky window manager. I suspect the answer is going to be "Use XMonad", but I'd like to know for sure.
