In particular, would love to see a payment method other than paypal. Google wallet or dwolla would be lovely if possible.
One thing to call out though (as a paid user now :D), we should really do some improvements to the forums. The look is very simple right now, but it's VERY, VERY basic. Even something like the below suggestions would be lovely, not sure if we have the users yet to warrant a larger forum, but community involvement isn't going to be incredibly high if the forum isn't easier to use and read.
