Sometimes I find myself needing to fire only one gun and so I deselect the other one and start changing angles to hit my target. When I need to use both sets of guns again the angles are all off and I need to either max out my angles or take them both down to 0 to make them both the same in as fast a time as possible. I think it would be a good idea to have a key that levels out the guns angles or sets them both to max or minimum.
