I think this may be a bit much, but like add on maker "ranks" based of total ratings/total downloads.
EX: 10, 5 star add ons means ____ has 50 points giving him the rank of Pro or something like that. This could disguish how much reputation the user has and the quality of his add ons.
Also maybe mini user profiles for the people that release add ons kinda like youtube, maybe not that extensive though. Profiles would show their RTB avatar, how many people have suscribed, their add ons, and how many of their add ons have been favorited (see below)
Basically an add-on gets favorited when a user enjoys the addon (bit akward) Anyways when an add on gets favorited when somebody views the add on to possibly download it, it could say somewhere: Favorited 3 times, or something like that.
