I bought myself a fancy new TLC 11 Nxtpaper Gen 2 with a cool e-ink type display. It’s an android tablet and I’m breaking free from Apple. That means no more Apple Books for my epubs. That also means, I’m now looking for a good solution to annotating epubs/pdfs (mostly highlights) on Android. I’d loveeee it it had some bring your own storage sync (webdav) or just plays well with the local storage for using syncthing etc. What are the best options?
