+If there is a token with only 4 digits (and maybe parantheses), assume this is a year, add it to tmdb search, retry search without 'year' if result is empty
+Show user file with title(s) found on tmdb, make user select one
+Remember selection and look in current folder for extra content (deleted scenes, trailers, featurettes) -> show user what files were found and have them select which files they want
+For each selection show file name plus try to match to extras category, show user selection of which kind of extra it is, then allow them to enter a arbitary name (prefill from file if possible)
