I'd like to request that the User-defined field mappings option be added to the Mac version. Our radio station has committed to using the DATE field in our FLAC files. I need to enter a release DATE separate from the YEAR for all files that I prepare to be added to our digital library. When I configure a "DATE" tag into the tag panel, any value I enter gets automatically assigned to the YEAR tag and my DATE value is cleared. And, our station long ago standardized on using TRACKNUMBER. So having its value it transfer to TRACK is a showstopper for us.

The current beta 9 has a hidden preference setting, where you can disable the default mappings all together. You can use Terminal.app and the command

`defaults write app.mp3tag.Mp3tag FieldMappingsEnabled false`

to disable the mappings. I hope that addresses the issues you're having right now.

Please also keep in mind, that this is a _hidden preference setting_ which can be removed in a future release, e.g., if I add something similar to the UI.
