I sometimes just want to audition a vocal track with a rhythm guitar to check if either has any pitch problems, while I am in the Tracks window, so I can cut and paste a better segment from another vocal track. I do this by muting all tracks except the two I want to hear. It would be quicker to unmute two tracks, than to go down the line muting 8-10-12 tracks. If there isn't that function in the Tracks window, that's ok, I'll just waste 5 seconds more of my life, obsessing over something no one would probably ever notice. ;-)
