It would be nice to be able to log out and log in as another user

After logging in, pushing the back button doesn't do anything, and there's no button to log out that I noticed. I noticed that the back button usually didn't do anything, but there were times I though it would be convenient to have. For example, it would be nice to be able to join two games at once, but I was locked into the game activity
