The bottom of the screen has one standard

Buttons anchored at the bottom of a phone screen sat inside the area iOS reserves for the home indicator — awkward to reach, and easy to swipe away by accident. This was wrong in fifteen places, each with its own hand-picked number.

One standard everywhere — the reservation sheet, the menu, the till, search, the assistant and the rest all clear the home indicator now.

The calendar's bulk-action bar used to draw over the dock. It clears it.
