Since Plex allows us to access our own servers, it would be nice if we can have a Evernote like feature, which is only allowed on Plex Pass accounts. The “Plex Notebook” should allowed text entry, notes, photos, PDF, recordings (like lecture notes), OCR of scan documents, etc: all can be searchable. Added features, “Plex Notebook” can be shared among other Plex users if granted by the owner. I have been searching for my own hosted Evernote like server, and it does not exist. Plex could provide this need.
I think Plex should focus on media like movies, series and music first.
