I bought a Supernote A5X last year, which is a fantastic e-ink tablet with a stylus. The company behind is very actively developing and enhancing the Supernote's (Android-based) OS and software and people (including myself) love them for it (see /r/supernote). However, I really wish their note file format was also supported by desktop software like Xournal++. Basically, I'm hoping that one day we'll have a standard file format for hand-written notes but of course I'm aware of the usual XKCD…
