Hi. Thx for a great app! Some thoughts on improvement: 1. Make horizontal sliders lighter or hide them to free viewfinder. We can change primary parameter by swiping horizontal anywhere on a screen, two-finger swipe will change secondary parameter, vertical swipe for focus. 2. Make focus slider more usefull, with scale and hyperfocal range (very usefull on such small sensor) 3. Make minimum visible in viewfinder shutter speed = 1/30, so we can compose on slower shutter speeds. Also i made a new icon, more "serious" and "meegoish" maybe you like it better:
