It would be nice if the Opera GX Web Browser could operate the way FRAPS or MSI Afterburner does and create an overlay (possibly toggled by a hotkey) while you are playing the game. The location and window size should be determined based on which game you are playing. I am currently playing a game where you have to wait for the game to get ready, then wait for the players to be ready. I am always flipping back and forth between the game and some diversionary web page. I think this feature would be the best feature, after preventing auto-loading continuously playing videos from eating up all your internet bandwidth while you are playing an online game.
