This is a no-brainer. Having the actual volume data on the audio track settings should be there 100%. When you’re making 20 - 30 adjustments on a project a minute, having to switch your attention to the mixer window (or open it on a laptop), or using the inspector when you just want a quick view (or quick grab and move) of the volume level is a waste of time.
Here’s how I have my track settings at the moment:
Ideally, it would look kind of like this:
Photoshopped volume data onto Audio Channel and Instrument Channel, and labeled / colored each track type so you can see a potential setup. With that new setup there would be a split second glimpse of the volume levels of all the tracks (with the option to the adjust it right there), while not having to go the mixer, go deal with the mess that is the inspector. The great thing about this - even if you use the inspector - is that you can adjust the volume from the timeline, without having to first select the track you want to adjust. Just like groups / fx, just grab the volume data and move it.
Pan would be very cool too - but that seems like it would have to be added to all channels, as it’s not an option on groups / fx either.
