Settings → Store has a new, clearer look: the settings are grouped in six blocks (who can see the store, orders and payment, prices and currencies, the store banner, returns, reviews and ratings), each with an icon, a short line of help under every setting and iOS-style switches.
Settings → Store: the store banner is shown full width with a preview of the new picture before you save, settings that depend on another one appear right under it, and the footer tells you how many changes are not saved yet.
