Im not sure if it clasifies as a came improvement but:

There could be an addons part for the server. so people can add there own scripts for there server to make slight changes to the game.

Example: I have a rambowmatch server, and I think I would like to make a script for the game so if someone kills people who don't have the bow 5 times they get auto kicked.

Or I have a deathmatch server and I make a script so say, if someone gets a 'Multikill' or whatever a funny sound plays. 'Your the man now dog!' or something

Now what this has to do with the game is this:
I dont know where the hell I place these scripts so that soldat recognises them and uses it when I put up the server. There could be a little thing that checks a folder for addons and when it recognises any it will use them when my server is put up.

I hope thats enough detail for you. anything you dont understand what I'm trying to get across just tell me.
