Mainly a dark mode for the main interface and some sort of audio reader instead of having to use TalkBack. I don't mind using TalkBack, but I still have to manually turn the pages and everything at the bottom of each screen. So I can't just like get into a book and sit back and relax and listen to it. I have to actively be engaged with it because as soon as I get to the end of a page I have to click the next page button and then restart my talk back reading.
