I would like to take better notes when reading books. Considering getting a kobo with stylus system, but most my books epubs, not sure compatibility, would appreciate advice. I also have a samsung z fold 3, and I find the pdf markup in samsung notes app to actually be really good, but I'm not sure I wanna convert my books to PDF just for markup reasons. Yet to find good android app for marking up epub, after briefly looking into epub and based on my basic understanding of ebook formats, I believe it's kinda simply a too hard technical problem to build an app around.
