Suggestion re thumbs-up/thumbs-down image rating

Delighted to finally test the beta. First suggestion: Change the rating system from the simple thumbs-up/-down to a one-to-four-star system or something similar; I'd like a bit more nuance than a strict up or down vote. For example, in my first prompt, I asked for a close-up of a human hand, with all fingers extended. As expected, all results were weirdly formed, and one had seven fingers. They were all "wrong" (albeit amusing, as I expect this to happen with all image generators), but the one with seven fingers is more "wrong" than the others. I'd like to be able to express that in a quick rating.  Of course, this certainly is not a deal breaker; otherwise, the whole system is very impressive. More commentary to come.
