Ability to see profile in game setup screen
When players join a game, clicking on their names shows an option to kick them out. It would be useful to also be able to see their profiles. There has been a rise of people using multiple accounts to cheat, or colluding with friends. Not being able to see profiles that have played frequently together in the past prevents us from kicking them out of the game.
That's why being able to see profile in the game setup screen is important.
