Totally agree on the concede button, both on the hole and match. I think the time should be a little longer, 4 to 5 minutes but that can be worked out. I would also like to see the match play results show more than the points for winning, you should get a negative for losing a match so the leader isn't just someone who played a ton of matches. Maybe losing 1/2 a point for a loss but I'm sure that they will work out some sort of rankings that makes sense.
Whenever someone quits the game I am playing, I always wait for the forfeit, no way I am letting them off the hook. I will just browse the forums or something for those 10 minutes, especially if the quit happened on the 9th or when they were ready to lose.
