Currently, there's a graph for your owned books that shows what percentage of your books are read vs unread. However, since books on The StoryGraph don't (thankfully!) have to be on your TBR even if you log them as owned, I think that graph would be more interesting/useful/feel less mocking if it instead had sections for read/on your TBR/not on TBR, or if that's not a popular idea, that there was another such graph for your unread books. I know we can already filter owned books by if they're on your TBR or not and calculate the percentages manually, but it would also be a cool graph!
