1. Allow people to assign someone to multiple groups. For a while this has been a large issue with Sourcebans. Since you only allow 1 group per SteamID it messes with giving people access to unbanning/editing more than 1 groups bans at a time. If I have 10 servers and I only want Joe to be able to mess with bans from 2 of them it becomes very difficult. Also, with zombie reloaded where you need to have a specific group in order to access the zombie admin menu.
2. Allow for team based bans for CS:S servers. Most of this has been already coded. Examples:
