Minor quality-of-life suggestion: I've been trying to read every book I come across. Assuming the game is tracking which books have been read, it would be great if the UI prompt to read a book changed from "Read" to "Re-read" (or something similar) for books you've already read. This would help players track which books they don't need to re-read. There are just too many for me to remember on my own.
