I know there's a part in the yearly wrap-up that breaks down the genres/moods of your highest rated reads for the year and it's usually my favourite part of the wrap-up, and I would love to have that feature for all-time read books. I'd love to be able to filter the books I've read and rated between 4-5 stars or something like that, and then get the more detailed breakdown of genres, mood, age, custom tags, etc. Think it could be a fun visualizer/insight into actual reading preferences (like maybe I read mostly horror novellas, but my highest rated reads tend to be epic fantasies, or whatever the case may be.)
