Make Plex self-consistent

Plex Web will display local extras for TV Shows – but not for seasons or episodes.

Local extras work just fine with editions. By design you should keep different editions in their own top-level folder – if you mix multiple editions in the same top-level movie folder, none of them will display local extras.

That’s not how different-quality versions work. It appears you’re trying to apply the handling of editions (different cuts) to versions by appending the file names with some tag. Plex doesn’t have a concept for a {version-...} tag in folder/file names.

Each episode can have different-quality versions and Plex will recognize those just fine. The Play Version modal will display some key characteristics of the video (bitrate and resolution). There’s a separate suggestion, discussing for Plex to display more information about each version in the Play Version modal.
You seem to be trying to mix editions and versions – that’s not a thing.

See above… there’s no such thing as a {version-XYZ} tag in Plex. Plex currently doesn’t have a concept for different editions/qualities of albums (see duplicate suggestion linked in my previous response).

In that case, this should be the suggestion for you (though it doesn’t seem there’s much interest in this feature at this point).
With the example given in your other thread, you might want to consider using Collections to group episodes or shows without the need to deal with any of those duplications.
