I would add to this that it would be nice to filter tags to exclude books I have read!

Filter Tags by Read Status

That filter doesn't exist because you shouldn't see books you've already read in Recommendations — if you do, it means a book isn't in the correct family, and if you could file a book ticket from the book page ("Report missing/incorrect information..."), that'd be great — and for Popular This Week it's just a straight ranking of the most popular 250 books so we show you it as is, but if you toggle the sort order to anything else, e.g. Last Updated, Title, etc., then you should no longer see any read books. If you do, it's the same deal as last time!
