When you enter fullscreen, a banner appears at the top telling you to hit 'ESC' to exit. If you're going in and out of fullscreen often, this banner gets very annoying. Is there a way to disable it?
But it appears "opera:config#UserPrefs|ShowFullscreenExitInformation" is no longer a thing. I just read through everything from opera://flags and couldn't find anything relevant. Is there another opera://<something> menu I can go to or a file I can edit for preferences like disabling the fullscreen popup message?
