Ok first off I wasn't quite sure where this should be posted so went out on a limb and guessed here. But on to the topic at hand. I would think it would be much easier and even safer if you would move the change graphics, hot keys, sound, and everything else menu so that we could change it before entering a game.
Changing your graphics levels and viewing your hot keys while in game is a very dangerous thing, that could very well get you killed if you do it. I would like it if you added it in the main menu screen as a button you click to open the menu, instead of having to wait till you're in game to change graphics settings or view your hot keys which cost precious time doing when in the midst of a game.
I don't think it would be too big of a hassle to do but i also don't really know. But it would make changing your graphics, sound, and hot keys much easier and/or safer to do.
