An option such that Auto-level is only applied if the photo is no more than, say, 5 degrees off. The Auto-level toggle button would become a button with which to cycle through 3 modes, say off-auto-on, much like the Flash button is. The 5 degrees threshold value could be user defined in the settings menu.
I suppose there might be users out there who would prefer to interpret the threshold the other way around, such that Auto-level is only applied if the photo is more than, say, 5 degrees off, but I'm not one of them. But perhaps we might as well accommodate those people too.
