The idea of a SGU file with a chord chart of all chords used in a RealTrack is one method of addressing the issue however the same information could be provided in a much smaller text file.


You mean a text file like https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=203529#Post203529
or just the chords C Dm Em Am F G ...
With the SGU it will show the progression like the Artist Performance Tracks.
