Rematch button

Just a suggestion: How about a rematch button for a finished game? Then there will be no need to go to the player's profile, invite and scroll through the games to the right one.... Much easier with a rematch button instead.

or a "match length" option for the number of games to play in a match (usually an odd number)

with alternating player to start next game (unless there is a "duo" option to start two games at a time)

would also require a "resign match" button
