Translucent shadows on Mac OS screenshots

Man, I love this.  Just recently found out that you can get a screenshot of just one window under Mac OS by pressing the simple and intuitive combination of Shift+Command+4+Space (similar to Windows’ Alt+PrtScn).

But even better? It adds the drop shadow behind the window in your capture.

And even better than that? The drop shadow is translucent, so you can actually place it into a layout and see the stuff behind the shadow.
