4.An Actual Dark Mode
A true Dark Mode in iOS is something that’s been rumored for quite a while, and it’s certainly something users want. Apple hinted at such a feature with its new skin for the Clock app in iOS 10, but since then, it’s left users hanging.
A systemwide, dark-themed skin is something that users have been requesting for some time, and no, the new “Smart Invert” in iOS 11 doesn’t count. An actual dark mode seems like it’d be easy enough to implement, though if Apple is planning the feature, it’s probably working to get it as close to perfect as possible.
