Add all id3v2 frames in the settings of Playlist available columns
The GTK interface allows to add and remove columns from the Playlist, but those columns are just ten out of the many id3v2 frames existent. For most cases, those ten columns available are enough, but now I want to sort tracks chronologically from "Best of..." / "Greatest Hits" / "Anthology" albums by using the "Original Date" column.
In the current state, the only option is to put the "original year track" on the "Comment" frame, which is not an option cause sometimes that frame holds relevant information about the track.
A question pops up to my mind: Why just ten columns are available in the Playlist, out of all id3v2 frames?
