I'd love if there was a status option of "do not read" for books that we know we do not want to read. Sometimes I hear about a book and decide that it's not for me, but I worry that one day I will run into it again and forget that I didn't want to read it. It would be nice to have a way to remind ourselves of the earlier choice. Maybe it could even be synced with recommendations so that the system will know NOT to recommend it?
