Aural and Haptic feedback

While not exactly “design” aural and haptic feedback can enhance the UX. So far haptic and aural feedback in the OS is kind of limited (ie typing on the keyboard).

It could be expanded to other areas like when you tap on the screen to launch an app, scrolling, gestures etc. Its something underutilized i think.

And obviously configurable in the settings since not everyone is a fan of sound and vibrations.
