I hate iOS Settings in general. I am former BE Developer (now too busy leading 20 Developers and 6 QAs) but man if there is a thing I notice right a way is User Interface, User Experience and how usable is something. I did not do the UI development in our web app but I have always cared about the UX on all of the tasks I used to work on as DEV.
The scattered Settings on the iPad and iOS are the first thing I noticed as iOS newbie. I always forget where the Adaptive Brightness setting is. Thanks to this forum I know now where the settings for the pro motion are because why would you put those settings under Accessibility. And why do we need separate Setting tab for Wallpapers and then for Display and Brightness as it is the same - Display.
