Toggle between Shutter Speed and Shutter Angle in main exposure menu.
There was already some discussion about this here. To make toggling between shutter speed and shutter angle easier, I think it would make sense to add it as a toggle. Similar to the way the Gemini can switch between Standard and Lowlight modes when in the ISO menu. Would clear up some confusion and also make adjusting this setting much easier.
Basic mockup. The toggle switch would obviously only be in the exposure menu, not the FPS menu.
