The TV Show scraper defaults to populating episode titles with the episode number when the episode goes unmatched. This scenario happens frequently when storing TV series’ special features from the disc, which don’t have an entry in the TVDB. It seems to me that a more natural and intuitive default would be to use the filename as the title, particularly the portion of the filename succeeding the season/episode descriptor. This issue is also discussed in https://forums.plex.tv/discussion/217256/tv-special-features-names-not-working
For example, instead of the following special feature appearing in the Specials season as episode 42 with the title “Episode 42”,
"TV Show - s0e42 - Deleted Scenes.mkv"
it would be much more useful if it appeared as episode 42 but the title “Deleted Scenes”. If a file doesn’t have such a name decoration, then the scraper should fallback to just replicating the episode number as the title as it currently does.
