I purchased Display Fusion in January 13th because it just seemed the best option for managing two displays, but now I am feeling the need of a tool capable of "set the mouse free" from a full screen game. This article shows the trick:
It uses a software called Actual Multiple Monitors from Actual Tools to perform the trick.
Could you add this feature in Display Fusion?
That's the important part of the text
"To resolve all these issues, you just need to do the following:
launch Actual Multiple Monitors
launch StarCraft 2
press the Ignore deactivation hotkey (Ctrl-Alt-Shift-I by default)
After that, you will be able to easily drag the mouse out of the StarCraft 2 window and work with windows on other monitors. This also prevents the StarCraft 2 minimization when you activate another window.
To restore the usual functioning of the full screen StarCraft 2, press the Ignore deactivation hotkey again when StarCraft 2 is active. "
We actually do have a Function for this in DisplayFusion. Just assign a key combination to the "Prevent Window Deactivation" Function on the Settings > Functions tab.
