When the picker renders
The picker only appears for a given selector (billing or shipping) when all of these are true:- The customer is signed in. Unwan does not offer saved addresses to guests.
- The corresponding selector is enabled in Accounts & Privacy → Unwan.
- The customer’s combined address book (see The Address Book Model) has at least one entry.
Picker states
- Collapsed summary
- Expanded chooser
- Search
When a selection is active, the picker shows a compact summary (recipient, street, location) with a single Change button — this is what a returning customer with one preferred address sees.
What happens after checkout
- A saved selection is order-specific by default. Choosing a saved address for this order does not silently change the customer’s account default — that would be a surprising side effect for something as routine as picking a delivery address.
- A new address entered at checkout is saved automatically (governed by Save checkout addresses, on by default), becoming a role-free additional address — unless it’s an exact duplicate of something already in the book, in which case the existing entry is reused.
- Promoting a new address to the account default is opt-in, via New address defaults → Make the new address the matching default. With this off (the default), the account’s billing/shipping profile defaults never change just because a customer typed a new address for one order.
- Billing and shipping don’t double-save. If a customer lets billing be used for shipping, or otherwise submits the same address for both roles, Unwan’s normal duplicate detection means only one additional-address record is ever created — see Default Swaps & Duplicate Detection.
