The thought behind this is to use the new DVR guide data and sources like thedvdb.com to provide an accurate reflection of a TV season’s content.
Right now Plex only provides information on what it scans, it does not tell you how many episodes are in a season compared to what you have, it does not provide any information on upcoming episodes, or tell you what is missing.
Good example to illustrate what is lacking, would be on a series information screen in Sonarr. It pulls its data from thetvdb.com and shows you all of the episodes for a season, future, past, missing, etc.
Episodes that are missing from the library, either future or past, could be indicated by dimming the thumbnail, or a clear infographic that tells you they are missing/future.
IMO, this would take plex to another level and would be extremely helpful in a DVR Plex world.
Thanks in advance for considering my suggestion.
