A friends list suggestion:
I think there should be an option to have a friends list, to play with people you meet in the lobbies, more than once. As in when your playing a game and you meet people you like or would want to continue playing with, there should be an option to friend them. As of now, if you want to keep connections with people you have to find them on social medias, which sometimes you don't want to give out to a public chat. So adding a friend option can make playing with people you might not know safer and easier :). There should also be an option to private message someone in the lobby and in game so impostors can talk to each other.
