I already made a couple comments but I thought I'd use this to build on my thoughts.

Suggestions:

1. As I commented, a search bar/filter function would be incredibly useful when selecting models, weapons or entities. Either that or just a textbox to directly type in the the name.

2. A way to give entities timed respawns or being able to respawn entities without resetting inventories.

3. Seperating setup and playing. Gamemode starts on setup by default where people choose their teams and admins can setup the game and an admin command/button that can then 'start' the game, sending players to spawn locations with reset inventories and can now score points and cannot change teams, naturally with a visual and/or audio cue (maybe even a countdown before they can start moving). I can imagine this would probably be very difficult and take a long time to implement, so just ignore if you can't be bothered.

Bugs:
- Also commented, when you're choosing a playermodel for a team, if you don't close the preview window before selecting another model you can't close that preview window (but a new one is still made for the model you just chose).

Questions:
- Is the SVN stuff really necessary? I didn't encounter any problems with hosting the server without it.
