The title is pretty self explanatory. When you link multiple things to the same automation track, it would be nice if all of those things were in it's title/header/whatever to help keep track of things. For example, if I link 3 tracks' volumes all to the same automation track, it would be great if that automation track had the name of every track in its header in the automation editor at least (instead of just the first thing you link to it). Big projects with many automation tracks get pretty crazy after a while, and deleting an automation track can cause a big headache if I don't remember everything that was linked to it.
