This is a minor UI update recommendation, but when I saw it; it made me do a double take. However, I really like the program so I thought I would pass it along. It would be nice if you reorder the color panel in the iPad Black & White Adjustment to match the Mac version. Also it seems more logical to be in the same order as a color wheel.
Color panel order for:
AP Mac: Red, Yellow, Green, Cyan, Blue, Magenta
AP iPad: Red, Green, Blue, Cyan, Magenta, Yellow
I have attached the relevant screen shots for you.
