// final commit (5 out of 5)

+ added new window selection highlighting (removed old one and functions related to it)
+ fully added functionality to capture child windows (this also enables to capture singe controls such as buttons or entire groups)
   hold SHIFT or ALT while selecting a window to capture child windows
*+ new target icon (made by me :P better visibility on black and white surfaces)
