Once you have identified which clubs/equipment you may want to purchase as you progress thru the game, how about the ability to add them to a 'Wish List' so that you can buy them directly as you reach the levels required without having to search thru the options again.
Me likey!
On a related note, for regular purchases like balls or drinks or whatever, it might be nice to have 'your' ball on a regular purchase list (here's what you bought before) as well as having the wishlist.
