I like a pause button, but that can also be a shifted function. the only admin button you shouldn't do without is an exit button. I have not added an exit button to my DK cabinet yet, and people get confused when they have to hit a button combo to get back to the menu. guests don't need to even know they can pause the games, but anyone who plays your cabinet will need to exit back to the menu, and without an obvious way to do this, it is confusing for them.
