Night Shift suggestion
We have
Settings -
Display & Brightness
(Dark to light)
Night Shift
(Colour Temperature)
During the day I need the brightness over 50% to see it clearly in a well lit room. During the night the screen is the only thing generating light, so I have to turn it down to less than 10%.
Being able to select different brightness' for day and night would be far more useful than a subtle temperature adjustment; its too subtle!
