I know it is first iteration and will be reworked, but there is some stuff I want to make sure you will take into account!
1. Multiple setups for the same mode -
Currently I don't think it is possible to setup two different CC modes sharing the same maps. One with GoalScore=3?TimeLimit=20 and one with GoalScore=5?TimeLimit=30, for example.
This will make even much more sense when mutators are in.
Ideally I'd like to give names to various setups, that would show up in the interface. Like: "CC 5v5", "CC 8v8", "Instagib CC 5v5".
2. Mid-game map-voting
This is low priority, but this is going to be required with community mods. Endless mods will come and we will need a way to switch maps

3. Majority voting, not counting bots - DONE!
I feel like the server should either immediately switch, or at least shrink the end timer when a map has been voted by majority, or when everybody (non-bot) has voted already. You increased the RestartWait to 60 seconds for voting, which is good. But if I'm alone with bots (or if we are only a few in general), I vote and then I have to wait all this long...

4. Voting for a current vote
In the voting interface at the top of the lists you can see the current voted maps ("comming up next" <== btw: typo there). Would be nice if I could click on it to cast a vote, instead of having to find it in the list below. That would make the UI more user-friendly and help with scalability.
5. Voting interface is too small
We can barely see 2 and a half maps in that column. There are only 6 maps and it's already hard to navigate

This is not even going to scale up to 9 maps. Not even mentioning custom maps...
You could expand that column and use some of that space available in the center!
