Whoa.  New feature in my Lenovo Screen Magnifier.  (At least, a new ADVERTISED feature.)

 

In the name of "accessibility", I think this feature is actually more useful than the buttons in Windows / OS X / most shells, as it allows you to use your secondary monitor in a way that is more difficult otherwise: dragging and then maximizing a window on a second screen.

Cool.  A free software upgrade of a utility that actually does something "novel".
