Any chance Display Fusion can implement a function to toggle black out (without powering off) a given set of screens on activation of keyboard shortcut?

This would be useful for watching Netflix or other videos or playing games for example when you just want one monitor to be active, but without turning off the other monitors / changing the active monitor configuration causing every window to realign undesiredly.

exactly what I was looking for!

Is there a way to create multiple profiles for the fading?
So I can have the cinema mode (blank out all not used screens) but also can use the normal fading (with other settings).
