"Postal / Shipping Address is the Same As Business Address" checkbox and auto-population of fields

This is a super handy feature which I got used to in Quickbooks Online.

If a Customer's or Supplier's Business Address details are the same as their Postage and Shipping addresses, it allows you to automatically populate the address fields simply by selecting a check-box.

It means you don't have to waste time manually re-typing/copying & pasting their details over for each section.
