I have been using Mp3tag for Windows for years, and I love it. One feature that I find essential is user-defined field mappings, which allow me to write equivalent tags across multiple file types using a single tag field (e.g. map "DATE" to "YEAR" for flac files, and use the tag entry field "YEAR").
Lately I'm trying to port over my tagging workflow to Mac, so I purchased mp3Tag for Mac this morning. However, I can't find this feature, which prevents me from using the application. Am I missing something, or Is this feature currently under development?
Thanks so much,
