Next step: Smart invert colors
A year and ha half ago, I pleaded with f.lux to develop grayscale. Now you have done it, and it's perfect. A thousand thanks. Next step: develop 'smart invert colors', like the smart invert colors on iphone: the screen is inverted, but photos, videos, and graphics are exempt from the inversion. If you guys come out with this, I will be impressed and elated.
