Help for Mappings

  1. In "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

is incorrect, because BAND is not user-defined. And this text is misleading in implying that only mapping to user-defined names is allowed.
