FR: Volume automation relative to volume fader

automation of the volume is relative to the fader, and so if i want to bring a track volume up or down we don’t have to edit automation to do so. The volume fader controls the maximum value and the automation is relative to this. what do you think?
i could use a plugin to do so! but it should be native IMO. Meanwhile, any VST just for this 64bit osx?

Sorry if i am being dumb, but in what way would that be different from using the current “Trim Automation” mode?

Or a VCA fader ?

thank you for the heads up!
