Ah, well if you're interested, the new manual colour balance allows you to alter the R G and B colour channels separately either with a simple click and drag, or by setting the 'stretch' and 'offset' settings. I think we might have a look at whether there's any way we can improve this further in the next version too.
I appreciate all your suggestions, and sharpness is something we will have a look at once we've conquered the new drivers.
