(As an option), for those using ACT for automation of their soft synths and effects, it would be great to have the ACT controller page come up with the properties (gui) page on the same Multidock tab to see what's mapped to what control device.

Upvoted! I use an a800 and when I'm working with only one screen it's a pain to have to look at the ACT plugin to see what the assignments are. I have to keep opening and closing it, since the plugin takes up so much real estate.
 
Possible alternative: make the ACT control bar module bigger, and display a param matrix there.

Thanks for the vote. Also agree with your alternatives if Cake were to provide a better means to keep the act window on top. (pin option for one thing).
