One would be a damage/death ratio rank system. This would work well in counterstrike as it cancels out all the lame people that wait and go and steal kills.
Another one would be a place on the menu with useful commands, that you can add and edit for your own personal preference. Saves us admins having to go into the console all the time, and saves us having to remember things
I think there was a couple more, but I can't remember now =[
