Still would love to have this feature. Strange for a stats based book reading site to not have this (though weighted average would be better)

This would make it really useful to find books for recommendations, because I'll normally look for books within a certain tag, but the ordering available isn't very useful for how I use it. I can neither sort by my own rating nor by the average rating, and both would be super useful for getting to where I want quicker.

I'd love this feature, especially if I could filter or sort all the recommended books by average rating.

YES this would make it so much easier to tackle my tbr. "Oh this book's average rating is below 3*? Begone, below average book!"
