Well...
So I can use the Analyst or Blue Cat FFTs broken out on other monitors for the tracks... but when I FlyOut the PC EQ I cover up the other EQs.
X-Ray (shift X) doesn't work on the FlyOut.
You can't float the FlyOut window away from the PC.
You can't control what it covers up when in FlyOut mode.
...
On the good side, it works well with touch, and when using touch you would probably not want to float the window around the screen and lose track of which one relates to which track.
The best I've been able to do is to minimize the PC EQ so that when I FlyOut the EQ it doesn't cover up the small EQs in the other tracks.
