Rating would also be nice!

those are great ideas, both were in our original wireframes but got stuck on the back burner in interests of getting the core changes made.. some other stuff we'll be adding in coming weeks/months:

lists: put your favorite add-ons and thems in a list for your project, that info will be used to create endorsement rankings later...

more badges: we've got em on users, and there's some attribute info on themes and add-ons already, but we want to make em sexier and searchable

preview/demo - as we get some more complicated add-ons we've got to have a place where you can test em out first.

buncha other stuff i've spaced but will remember as soon as we sit back down with our original wireframes.
