I really would love something like this! Tropes are a big filter when I research new books I want to read but I would also love to see them summed up alongside the breakdown for mood and a separate pie chart in the stats section. I suppose I could manually track this with the custom charts feature but with a large TBR and reading history, it would be very time consuming, especially as it seems that there is the infrastructure to filter by tropes already in the database.
