I know the feeling, I’ve been waiting for this since I started using Plex. I use Calibre for my books and Comicrack for my comics now, but both aren’t what I seek compared to Plex. Metadata, syncing, ‘read’ status like watched status, sharing,… are all very nice in Plex and it would make Plex the ultimate media server

Ditto

I’ve tried Ubooquity as well as those 2, currently just have them in that at the moment. That lacks some serious sorting options though, especially for big libraries author and title doesn’t cut it ha. I myself would love it if Plex decided to manage both, I wouldn’t even care about much of a scraper if we could somehow pull out Calibre data. Tracking and read lists would be a must though
