Add menu and score keeping for type of game played I.e. : stableford, skins, match, etc.
Sometimes we play skins, or matches. It would be cool if you could select the type of game you are playing and have the unique scoring of those games be calculated in addition to gross scores on the scorecard. It's a feature Gamebook app has that is cool and they've got a great list of games along with brief description of rules. Your interface is much better though.
