I would like to render more custom stuff on the screen, but it won't be very user friendly now because it will always render on top of everything else. Changing it to render under/over PW windows is doable, but requires some extra work.
First thing that comes to my mind is custom labels on skills. If you can assign hotkeys to all 3 rows of skills it's easy to lose track what's mapped to what. Labels could clean that up. I can add them them in correct position on the screen but right now they will show on top of everything else, e.g. the main map when it's open.
