You can SHIFT click to turn all tags off. Then right click one tag to show this tag.
The only advantage of isolation mode is that when finishing isolating, it returns to previous configuration. If it is all tags on, you can work without isolating by SHIFT clicking again and it turn on all tags.
all the problems come when a track has more than one tag... my brain is not good enough for all these logic issues
I'm working on some special tags... that are dynamically assigned automatically.. so you don't need to manually tag tracks with them. for example like (Empty) for tracks that have no items... (Folders) for folder tracks... etc. suggestions for more new special tags welcome. They are shown separated at the bottom of the "normal" tags list.
