I'd like to see...
1. A Driving Range - like at a real course where you can just test out your clubs in different wind conditions for distance and practice shooting straight.
2. Practice Putting Green... where you can pick it up, drop it in another spot, shoot, repeat...
3. Funny stuff: Kick the ball out of the trees for two strokes
4. Funny stuff: Pick up your ball and throw it for two strokes
5. An animated caddy - the less you pay him the more annoying he is or makes mistakes in his club suggestions
