Massive UX improvements for one-handed use. iOS 16 is iOS 1 with some extra rows of icons. There are too many interactions requiring the top third of the screen. Thus:

1. Position icons anywhere on home screen

2. The multitasking screen made better use of for:

- Notifications stacking at the bottom like the lockscreen. No more pull-down blind.

- Control center sits as a RH-panel on the multitasking screen. Replaces the camera swipe on the lockscreen.

3. Universal screen edge back gesture ripped from Android. iOS already has this in some apps but it isn't universally integrated.
