Support on other OS's
I've just posted on a musical forum singing the praises of f.lux since I am a very happy user on macOS 10.14.6.
I posted that it was available for "all major OSes" and somebody pointed out in typical forum "I think you'll find" manner (!) that "All 'major OSes' already have that natively - definitely both Windows 10 and Linux Ubuntu/pop!_OS".
Does anyone have any thoughts about such claims or why f.lux is a superior solution to the problem?
