Take Instant Screenshot should have the option to follow the default display (uxer agent)

So I’m working in display 1, uxer agent set at display 2, when I want to take screenshot, I want to be able to set to follow the default display as uxer agent.

Right now, I’m forced to use display 2 as my main working display because the take screenshot is always go for display 1.

A different case from my previous feature request.
