"Lighting at Night" menu?
I can't find this option... as per this FAQ entry:
"You can look in the "Lighting at Night" menu and choose "Expand Color Range""
I'm using the latest beta release, is this not an option anymore?
The FAQ only applies to the latest stable release, version 3. When the beta replaces version 3, then they will likely update the FAQ.
Anyway, yeah, the menu is reworked, but nothing is removed. The range is expanded when you restart your computer after installing f.lux, so there's no longer a need for an option or button to expand the range.
It's in the "Change color to..." menu.
We changed this menu to affect the "current" setting rather than the "nighttime" setting.
