Hi, In the development and the photo personas, there are adjustments missing like "Saturation" for example. I think also that you should group some adjustments like for example : Brightness / Contrast, Shadow / Highlights, Black point, exposure, etc., because they all have to do with light and they need to be together in a group. Same thing with saturation and vibrance, they belong together. I personally don't like the thumbnails for the adjustments you have in the "Photo Persona" mode. The thumbnails are probably the reason why you split all the adjustments. To me, it makes the interface way to complicated to use, and professionals don't like to see a preview of an adjustment, if they know what it makes. Other users can try out.
Anyway a good app that I will buy...
