I LOVED the new tagging logic. I felt that it was important to be able to change the filters while you are tagging, therefore I was not using the "on filter" tagging at all, because it was not practicle to go back and forth.
Nevertheless, (here comes the bad part), I still want my tags to be more protected. (although I cvs them everyday). I don't want my wife, or kinds (I don't have any but I could) change all song names to "Yellow Submarine", while trying to select a song.
Suggestion
Keep the tagging toggle button. If it is off, I would have the check marks, but not the boxes. And no change would be allowed. If it is on, it will work as it works right now. filtering/tagging together.
Minor suggestion
use different color check mark (i.e. half tone), instead of "box" style check box.
An issue that got worse:
The check boxes mean even less space for filter/tag values. I need to select them, but I can't even see them. I suggested multiple solutions for that problem before, and I know that you experiment with auto sizing. For now, tool tips would be a simple temp. solution.
MC10 Suggestion
Access rights. I.e. let people create their own playlists, but don't allow them to change others. There will be people that have tag changing permission and people that don't, etc. Even for a single person, I would use a user identity to use MC as a jukebox, and admin identity to make database changes.
