Traktor needs the ability to show custom columns for additional fields in ID3v1/v2 tags.
I spend a lot of time curating data about my tracks. It isn't possible to show or organize these fields by the established column types.
It shouldn't be difficult to configure Traktor to accept a list of tag field names for custom columns. When a custom column is visible, it should show the values of the field for any tracks that include the field in the ID3v1/v2 tag.
