I would like to be able to see how much is left on a ball before I start playing. So I don't accidentally start a round with 1 ball that only has 7 hits left on it.
Also, the FAQ mentions that if you run out mid-round, the ball will be replaced with the same type AND color if you have them available. Couldn't that just be same type only? I don't really care if you switch me over to blue balls if I started with green ones and ran out. That's way better than being stuck with the default ball.
