Not sure if this is possible - and maybe only useful for challenges with many many participants - but I think it would be super nice to have a way to "sort" the books added by others to a reading challenge prompt. Possibly by the parameters already available in stats (moods / pace / genre / fic vs. nonfic)? I would love to use the list to get inspiration for my own reads, but would like to have some way to tailor to my preferences a little bit more!

What would be super lovely (but also deeefinitely realize I might be asking for too much here), is getting (a few) recomendation combining other user's additions and my reading preferences. e.g., a "we think you might like these" section with ~5 books.
