let windows be docked together so that they move around the screen together, and open/close together until they are undocked.
option in preferences to enable autodocking plugins to eachother when added to an a channels insert.
Maybe something like this would be possible with a Windows Application like Aqua Snap. Buts thats just a wild idea.
I have no idea how well apllications like this work with Cubase and VST Plugins and have no time to try it out at the moment.
