I possibly spend more time listening to audiobooks than I do consuming any other media, and I have a fair-sized library of audiobooks, so I would count myself among those very interested in audiobooks.
But I also note that Plexamp currently lacks almost every key feature required of a good audiobook player, whereas there are existing audiobook players that have all those features and have “good enough” PLEX integration as well.
If the PLEX server treated audiobooks and other long-form audio like dramas, lectures and (maybe) podcasts as a specific media/library type, then it would make sense for Plex to develop a specialist audiobook player, whether that be added fuctionality to Plexamp or a competely separate app (which would be my choice). Audiobookshelf is going down this path, but it still has a long way to go, so there is probably a market opening there.
There is a very long-standing feature request for the PLEX server (rather than just Plexamp) on this below. If you want to burn a vote, maybe burn it there.
