No. That is not what I mean at all. But thank you for trying to understand!
Workspaces are not going to change focus. It isn’t about ‘what things go in which monitor’. It’s about what is currently selected.

Here is part of post #1. Hopefullly maybe it’s more clear? I darkened the main part.
“Now in Cubase 7 (with many, many, many more things that can be changed on the mixer)… those key commands ONLY work if the mixer is “selected” and on top. So… if I am editing in the arrange window and it is selected, my key commands to change the mixer views don’t work!! I have to first click the mixer with my mouse to activate it, then the key command will work.
HUGE workflow loss for me. 
This also affects hardware controllers like the AVID controllers. The mixer key commands assigned to buttons on controllers don’t work UNLESS the mixer is selected!!”
Hope that helps!
