Hello,
currently the Content tab in MarginNote shows the document outline for PDFs, which is quite useful.
I would like to request that MP4 video chapters and M4B audiobook chapters are also displayed in this tab. While MP4 is supported but the chapters aren’t recognized, M4B currently doesn’t seem to be supported at all in MarginNote.
Chapters would make it much easier to navigate longer videos as well as audiobooks.
Thanks for considering.
