Whenever you search for books and sort by average rating, all the books with a 5 star average due to a low number of reviews are at the top. This makes it so the actual highest rated books are buried under countless pages of books with only a few 5 star reviews. It would be nice to filter these out to see the actual highest rated books. So for example, a filter that would allow you to only see books with say, 100 reviews or more. Or just make it so any book with less than a certain number of reviews automatically gets filtered out when searching and sorting by average rating.
