With the new update I was thinking more about the mood chart and I started thinking about how the moods are distinct from each other in the chart, but books usually include more than one. I think it would be really neat to have some way to show how often moods correlate with each other. For example, a book that's funny and lighthearted is pretty different than a book that's funny and dark. Looking at my top two moods, a combination of them accounts for about half of #1 and 2/3 of #2, so it would be interesting to see what the other related moods are. Right now, if we click on a bar, the book list ONLY shows the mood we clicked on and not any of the others that the book has, so it's kind of difficult to see easily.
