Having a player with 2 characters
I don't think there's any way to entirely do away with the drop-down, Piestar, but maybe you could reduce having to deal with it? If one of the characters is the player's primary character, and the default to primary character option is checked on, it should (I'm guessing here, because I can't go test it myself) eliminate the drop-down showing up at least in the group that the primary character shows up in?
I think, at least.
