Log-out Button

I would love to have a Logout button in league of legends when im swapping accounts, i often play on eune and then after some games i relog eu west to play with my other friends. relogging is really unsmooth because i have to exit the game then start it again to be able to change region and then log in to eu west and play

Just being able to press logout and then coming to the Launcher would be much smoother and easier :)
