I would suggest that there be a simple way to forfeit without waiting for you turn to do so. Most players just leave without forfeiting and that leaves the other players stuck waiting for the time to expire before they can proceed. Many players do not want to wait that long and also leave the game which destroys the round for everyone.
If there were a forfeit button that was there for them to use in a simple way it would speed up the game and keep the round going for the players that are left.
