F.lux doesn't work for very northern/southern countries (e.g. Finland)
I'm living in Finland. At the moment, sun rises around 9.40am and sets around 3pm. The default "curves" in f.lux are unusable for me:
I've been now using my computer for an hour, and f.lux is still "sleeping". I would like to see white light in the morning to wake up!
Couldn't agree more. The beginnin and end of preferred "daytime" should be customized.
Or maybe there could be another buttons in addition to "when i wake up": "when i go to sleep".
