While I can see the positive sides of linking faders, it is somewhat not so important. Maybe it is for other hosts that don’t have the so called “folder tracks”.
Yet with Podium one could assign the tracks to a Parent Group Track, and from there on control their Volume, Pan etc. values and automate them respectively.
As for the inverted linking, I prefer the automation route. And yes druid, it will inevitably cause visual clutter. It is exactly this matter that I have thoroughly examined in one of my previous posts, i.e. Automation feature requests.
It would be quite a bit cleaner and tidier if we could put the automation lanes on top of the track, no matter how many, and when needed choosing from a list which one to show, as well as be able to work with the MIDI notes and the aut. lines simultaneously, without one disabling the other.
Peace
