I hope you can add an option to have a page flipping ‘animation’ whenever going from one page to another that is similar to what it would look like in real life. Instead of the usually swiping to the next page, we would need this animation feature to add more fun and simulation to our note making process. Additionally, this would dramatically make the app more real to life. Personally, this would make me more engaged (and happy hehe) when flipping through long textbook PDFs or my digital notebooks. It would be such a joy to have these feature, and it could overall increase productivity and pleasure in the app.
