+1 Thank you! Your post builds on the rant I've wanted to make whenever I hear someone make a similar request / complaint about lack of a night mode -- I'd just like to add my $0.02 (or maybe $0.04): 1. For thousands of years, text has been dark (or colored) on a light background (at least, after cuneiform) 2. I used to work with people and use shared computers with green screens -- every time I came to use the computer, the brightness (and contrast) would be turned all the way up, leading to screen burn in (and a health issue with my eyes) > Proper calibration starts with "the light level of a white screen on your > monitor should match the light level of the walls in the background."
