Is there a way to have Mp3Tag show all the tags associated to a file? Something like a "ShowAll" master view? I cannot add the Short Description using the Mp3Tag tool directly. I am forced to copy past many times in iTunes which is tedious. I want to add test data, such as "xxxxxxxxxxxxxxxxx" using iTunes and then use the "ShowAll" to see which field I need to edit rather than random trial and error. I think iTunes changes these every once ina while. The files I am editing in this case are *.m4v files.
I've added a screen shot of the iTunes and mp3Tags Extended Tags view from version 2.93.
