The icon is smart but I don't really like it. Prefer the night lamp they have been using, it is more charming and obvious.
Can't wait for that feature though. Avid user of f.lux on Mac, tried it on iOS some 3 years ago on jailbroken devices.
Anyway, low power mode toggle when. Better screen rotation options when.
I guess night lamps are too skeuomorphic. I can't live without the feature now though, toggling it on and off in the evenings really puts it into perspective how harsh the cooler standard lighting is.
+1 for a low power toggle. What kind of screen rotation options do you miss?
