How about a setting for gamemodes with limited lives where you use the coloration in the player list, normally used to show who is in the same minigame as you, to show who is still alive?
Also - you have a setting to shuffle teams every few rounds, but is there a good way to swap teams every round but periodically shuffle them? Shuffling currently functions as swapping when you only have two teams, but if one team is becoming better than the other, there should be a way to fully scramble them.
