Help for Mappings

  1. In https://docs.mp3tag.de/mapping "User-defined field mappings" (or elsewhere) please document the Options, Mapping, "User-defined field mappings" table in particular more-clearly define Source and Target, saying that Source is in the audio file and Target is in the Mp3tag UI. And please provide an complete example.

  2. I think
