Add fully histogram color stats and a zoom option to put the points in the correct places in the curves. This will help a lot when using curves!

I'm considering a rewrite some time to place the curves on top of the image, so you'd get more fine-grained control. Zooming is one option, but I fear it would end up complicating things. Have you tried curves on the iPad?
