Good for: Letting online music streaming continue playing without accidently closing it while doing other things Playing games in class, browsing facebook at work, etc (we don't recommend it for this) Features: hide/show any open windows; password protect any hidden windows; unique covert browser feature; press one key to immediately: clear the clipboard; mute the speakers; hide/completely close the covert browser that is open. Best of all we can add almost any feature that you suggest.
