Whenever you want to scrap something on the screen,
you probably used Cmd+Shift+4 or some other apps.
But, as you know "Cmd+Shift+4", which is "screencapture" app included in Mac OS X, simply saves the captured image on the desktop rather than shows it to you instantly.
So, I made this! This app grabs anywhere on the screen as images and shows you instantly.
Cmd+Option+B: Grab It!
Drag: Move Images
Double Clicks: Make Images small
Right-Click Drag: Drag as a file
Cmd + w with mouse on the image: Close the image
