what is "expanded daytime settings" setting?
Found no reference to this in the FAQ and don't know what it does. Does it have something to do with DST?
As a side note, I LOVE f.lux but you guys really need to consolidate your documentation into one place. I couldn't even find release notes for each version -- unless they're buried on the site somewhere.
We usually recommend that people see daylight during their day and less light at night.
But some people want to have really-warm colors during the day, so we made it one more step to turn this on.
So "expanded daytime settings" actually does not mean more daylight? Sure, makes sense.
We have a small minority of our users (<<1%) who try to avoid all blue light due to headaches or other reasons.
We don't think this is a good idea for most people (as explained in my 2015 post), so this is a rather hidden feature for those people to get more extreme settings during the day. By default, we limit the range.
But right now we don't know of a way to make a white screen any brighter.
