BookShelves
BookShelves already lets you rate books (0–5 stars) and mark them as favorites. While there’s a Smart Shelf for favorites, I couldn’t find a way to browse or filter books by rating.
It would be great if ratings were supported in Smart Shelves and search/filter options. For example, being able to quickly see all 5-star books, books rated 4 stars and above, or unrated books would make the rating feature much more useful.
Thanks for the suggestion! You're right that ratings are currently limited to individual books and the sort option, but aren't available as a Smart Shelf filter criterion.
Smart Shelves are already on our roadmap for expanded filtering options, and rating-based criteria (e.g. "4 stars and above", "unrated") fit naturally into that. Thanks for reinforcing the request!
