I would find it so helpful to be able to filter the stats by how I rated the books (for all time, but by month might be fun to compare as well). We can see our average rating for the genre/mood across all books I've read but I think it'd be really interesting to see, for instance, if it was showing only my 5-star ratings, what proportion of those were magical realism vs. fantasy, or dark vs. lighthearted books. It would give me an idea of my preferred reading tastes and what I'm actually enjoying rather than just what I've been reading mostly.
