I would like to request the Multiple Tag Splitter for the "Language" field. Having a song sung in multiple languages is just as common as a song sung in a single language. While you can split multiple languages with a semicolon and it works fine for filtering purposes, adding languages to songs is cumbersome because MusicBee lists each unique string you've entered into the field as a separate entry.
This field should act like most others and provide me with the "..." so only a single value is suggested when I type.
