At some point I also made a virtual bookshelf but for a different reason: I found that I often didn’t remember what I read about. So I started taking notes while reading and also making pixel art covers for the books I’ve written about. I feel that writing down ideas makes it easier to revisit them.

I love that the OP made this app for themselves, enjoyed the result, and shared the journey, so that we could all have this convo. With that said, I feel that you've done what this "should have been" IMO. It doesn't have flashy spring motion scroll, but it does interactively capture what I'd care about, which is recording whether I've read the book, what I found relevant/important/memorable, and how it connects to other things I've read/thought about.
