I think it would be a good addition to be able to go into settings and changer rather you go to social lobby, practice arena, or back to menu when hitting the rematch button

Something you could add onto this is to be able to adjust some settings of these areas, being able to change lobby to previous lobbies you've played in, being able to change social lobby to night and day, or being able to change practice arena to any settings you want just like a custom game would be some to name a few.
