I finally have a chance to play around with this and I LOVE IT. Will make big manual editing projects so much easier because I can show only the fields I need.
It's a little disorienting that the Work/Movement fields just don't show up if the track isn't a "classical" track. Maybe they could be shown but disabled? Also, it seems like Movement # and Count could be side by side, like disc number & count, etc.
Thanks!
