I would like to see Playlists treated as their own container, similar to how a TV Show would operate with its seasons and episodes inside. When an item within the Library, whether it be a Movie or TV Show, is launched from within the playlist, a tag with the playlist ID could be added to the request for playing the file. If the item is stopped in the middle of the item, it retains the playlist ID tag, so when launching Plex again either later or from another device, you are continuing the item from within the playlist. As an item is watched, you continue through the playlist. Once you stop watching and start Plex back up, there should be an On Deck item for the playlist items, but NOT their original container. I have seen posts related to this issue as well.
Usecase example:
I would like to create a playlist for the Marvel Cinematic Universe which includes both Movies and episodes from the shows as well. If I close Plex while watching an item and then come back to “Continue Watching,” I am no longer watching that item from within the playlist. I am watching that item as a standalone and once finished, I have to go through the process of browsing to the playlist again and find where I left off. In the case of having a mix of Movies and TV shows, the amount of items in the playlist could be rather long and tedious to browse through each time Plex is re-opened.
If the playback of the item, TV Show episodes in particular, is kept within the playlist container with the associated playlist ID, this should also avoid issues of causing the Show that the episode was played from within the playlist as showing up in the On Deck list unnecessarily.
