I currently have 2 monitors and use DisplayFusion to help control them.
I prefer to have my monitoring software (i.e. Aquasuite) running on the smaller monitor to the side (system monitor 1 for me), and use the larger monitor for primary functions (i.e gaming).
I can set Aquasuite to start on the side monitor (1), but when I implement the Desk-Top-Display function of Aquasuite, it always goes to the main monitor (2).
There is an option in DisplayFusion to force a program to run on a particular monitor, which I have set to monitor 1 for Aquasuite.

But Aquasuite must control where the Desk-Top-Display shows at some lower level of control, as the Desk-Top-Display continues to show on the designated Main Monitor (2 for me).
The request is that in multiple monitor situations, the monitor used to display the Desk-Top view on be user definable.
