Here’s a thought to consider: if dynamics are already linked (or grouped), would it be possible to grey out that option in the right-click menu, so you can instantly see what is already in place? Sometimes I’m not sure whether things are linked, or grouped, or both. Seeing what connections are already in place would help me select the opposite option.
This might be helpful with things other than dynamics, but I’ve haven’t thought that through enough yet. Or is this a dumb idea? Since these things don’t show in the Properties panel it would be nice to see the connections somewhere.
