Please add ability for making screenshots with time interval (capture every 5,10,20 sec)

Please add ability to "save" captured screenshot in windows buffer (like standart prinscreen)
Will be good if realize in next version.First we will probably introduce multiple screenshot capturing option with user defined time intervals.
Also add ability to set "capture screenshots" at "PrintScreen" button and other hotkeys to NumLock keyboard, pleaseAbility to set recording hotkey to "Scroll Lock" button (LED on keyboard will indicate recording process).
