While there’s no option to post to social media you can now create hubs on your home screen based on collections (smart collections based on filter criteria or manually curated ones).
This requires PMS 1.22.3 and Plex Web 4.56.3 (currently only available in the hosted web app) or Plex for Mac/Windows 1.31.0 – publishing collections to the home screen also requires a Plex Pass membership.
Not 100% sure if this is covering the extend of this suggestion or if there’s more components I might have missed…
