I don't think I've seen this suggested, so I'm going to suggest it here.
Locking someone in the brig to behave was a GREAT option. Thank you for adding it. It's fun to play around with in game with friends, and useful if you have a troll that is ruining your game to put them into the brig - make fun of them - and hope they get bored and quit.
It's that last part though that is essentially annoying. Yes, we can mute the voice / text chat of the person we put in the brig if they are a troll. But we had a rather exceptional troll last night that stayed around for almost 1.5 hours! Because of that, we were basically a 3 man team for most of our game. So after X amount of time in the brig, can you have a new option pop up in the menu that allows you to "kick" someone from your game? Again, still vote on it together, but give us the option to actually get rid of the person if they are persistent and stay around.
