on iPad Pro, can't save image!!! – Luminance Review

I love this app for one feature alone: individual color control. But on the iPad Pro there's no way to save the edited image to Camera Roll, email, copy, or print. Only sharing to FB is possible. That's crazy. What good is the app if you can't save the image to CR for further editing? Meaning, you can't get it out of the app! Please fix this!
