Not that I’m aware of. Closest thing would be the toggle in the automation envelope box which lets you filter out parameters that are not automated. I use this constantly, very handy. But it does require you to switch between parameters.
And, eh, I can always tease you with mockup pictures. One is allowed to dream
As a tool author, it would be pretty nifty to have access to the envelope editor… then we could actually write this sort of thing ourselves
Yeah, I liked that mockup, but I don’t really need to see the whole development over time - just current values, ideally as a dials.
Something similar to Instrument Macro, but instead of being restricted to just the specified instrument, connected with whatever parameters I’d like.
It doesn’t even need to write to them, just for overview 
What I really want to achieve is to have my MIDI controller control several parameters and that I could see where they are without switching tracks & windows. Isn’t your Duplex tool doing something like that?
