This floating bar will remain visible while the mouse remains over it (or, alternatively, will only be hidden when the mouse leaves it for long enough). See DVD Player for a comparable UI but note that its implementation is slightly flawed since there's no delay in its slide down. When the mouse is moved to the top of the screen and left there for longer than an instant, the menu bar and also a floating bar (with the normal set of 'bar' controls, including a tab strip) will slide down.
