Saw this suggested a few times before, but each of those threads are now closed (2 years ago and 6 months ago, respectively), and thus can't be voted on, so suggesting it again! It'd be swell if we can have a rating/review system for the marketplace. Buyers could leave a star rating as well as a comment about what they think of any particular set, which could be very useful both for other prospective buyers to see what other people thought of a set (quality, etc.) and for the content creators to have a means of viewing feedback on their particular sets, to see if they should be creating more of X style because it's well-liked and popular, or perhaps if they need to clean up something about a set because of a minor alignment issue or whatnot. Ideally, ratings and reviews should be editable, as they can change as a resource updates.
