Ok,you know that opera is infinitely customizable.You can moove around pannels,toolbars and buttons whereever u feel comfortable.
Now using javascript,you can make custom buttons that do special and usefull tasks.
For example,while using the Full screen (F11) u really need the tab bar and the address bar to do anything usefull.To do that u must exit the full screen mode and again go back to full screen.Now you can add those two to the full screen layout and u need not go out of the mode ever!
