I really miss not having it there and I’m pretty sure I’m not alone .
If you right-click on the word Play in the track itself, you can solo the track, or left-click to mute.
Similarly, from the track scopes view you can right-click on any track scope to solo that track, or left-click to mute.
What more do you need?
I always used right-click on scopes or right-click on “play” in tracks.
Now that I didn’t know , cheers
