Good Direction

it is simple, but I like it. it does exactly what it says, and i like that. i have tried to find a easy way to add some fields to my checkout, and there just hasnt been one out the, until this guy. i like that loushou is updating it too and adding new features already. granted, this new product cat field feature only puts the fields on the page, but that is the hard part anyways, right? anyways, thanks @loushou for a good start, and keep up the good work
