I use the audio fader on the Inspector panel quite a lot and its frustating if I’ve e.g. been to the Track Versions tab, that I have to click twice to get back to the audio fader. 1 click on the Instrument tab and 1 click on audio fader. Would be nice if it had its own tab outside of the instrument tab.
Another solution could be to add a key command for “Toggle Audio Fader” (and while you’re at it you could make one for “Toggle Track Versions”) in Inspector.
