Feature Request: Option to mute servers/DMs during game play

Just a suggestion from my end, maybe add an option to servers under the Mute menu that adds the option to selectively mute a server or DM while you're in-game to prevent clogging up your screen if you have the overlay enabled. 

I think it would help with especially streaming since the user may want to receive certain messages whilst in game, but not everything and it would be easier than manually muting and unmuting specific servers/users one by one each time you're going to game.
