I might do that, if so it'll be variations of this window here.
I'm not sure if I'll stick with this design, but it's the only one I've been able to come up with that doesn't entirely suck.

Edit, added an outline so windows on top of each other will stand out.
Working on the overlay, thoughts so far?
