You might want to add a few admin buttons (i.e. Pause, Exit, Tab, etc.)
In my opinion, if I were to redo my CP I would first get a bunch of iL supers, Ponyboy sells them on the Buy/Sell/Trade forums. (I find that the Happ supers feel really nice, they are the exact same as iL supers)
Hope this helps,
