There's really still no way to organize special features (trailers, DVD extras, etc.) for movies?
The scanner should really just support something like:
Movies/Inception/Inception.(2010).mkv
Movies/Inception/Inception.(2010).extra.Dreams.mkv
Movies/Inception/Inception.(2010).extra.Extraction.Mode.mkv
And group all the files tagged with "extra" together in a sub-category of the movie.
