For Light and Color and Effects options, it would be great the have the changes visualised live on the image while dragging the knobs, and not just when dropping them.

Came here just to second this, the results you can get with this app are absolutely incredible, but editing with live preview is so much better than without it, this would make this app a no brainer for me
