Source side track-specific Audio muting and soloing
In posts going back to at least 2015 there seems to be an ongoing longing for convenient source-side muting.
For instance

Taking this to the Timeline Panel would make it even more powerful, convenient and efficient, basically giving the same "S", "M" and Video muting buttons to Source-side tracks.
Since that would considerably widen the track control area of the timeline, a little column-tightening wouldn't hurt either.

How would you like the feature to work?
Add the same Audio "Solo", "Mute" buttons, as well as the video muting to source-side tracks of the Timeline Panel
Why is this feature important to you?
The ability to monitor, sample, isolate -- basically know what's going on in a source clip or sequence is an big efficiency/power boost when editing.
