Full screen videos, should allow mouse to show/access Panel apps/widgets.
When playing a full screen video such as YouTube, if I want to access any of the apps/widgets on the panels, I have to first exit full screen. This is inconvenience as to many times I would like to view System Tray info, time, set volume, etc. while watching a video without having to exit full screen.
As an example, on the Mac, when you move the mouse to the top or bottom of the screen the menus show up and you can make selections from the system tray. Also if you run another app, the full screen app is minimized. Then to restore it, you can just click the app in the dock.
Right now, when you move the mouse to the top of the screen, all you get is an X to exit full screen video.
