I think this is a fantastic piece of utility software, and use it almost daily.
I have Alt+PrtSc configured to take a snap of the currently active window. Occasionally I have applications that capture all keys and I cannot easily capture a screenshot there and then. Examples of this are guests in VirtualBox or pretty much most Remote Desktop programs.
The work-around is to toggle delayed capture, hit Alt+PrtSc and then focus back on the window I want to capture and wait. Oh, and then remember to toggle the delayed capture off again.
It would be wonderful if I could define a key combination to take a delayed window screenshot. The process might then be {key-combination}, focus on fussy window. Wait a couple more seconds. Done.
Thanks!
