Recently I found an AHK script called ScreenClippings
It has a feature where you can capture a portion of the screen and it becomes a floating panel.
This is very useful if you need to use the area as a reference. Sometimes I do this in certain dialogue windows and then I use the information somewhere else.
Also, I like being able to capture an area by this scripts hotkey: hold win key and draw with the mouse. To me this is a much better way than pushing a hotkey and then drawing. The ahk script allows me to draw the box immediately and not have to wait for the crosshair lines to appear. I just draw the box and the image is captured - it's so fast.
Maybe ScreenshotCaptor could do these things too?
Also, a weird thing happens. When I use the script to capture an area (by holding win+ctrl and drawing a box) then ScreenshotCaptor thinks I'm trying to capture a particular object (SC's hotkey is alt+printscreen), but I haven't pushed either alt or the printscreen key! Weird!
