On the Custom domain page of a Store or a website, each DNS record in the table shows what Magpie's last check found: Found, Not found, or Wrong value. For a wrong value, the value Magpie found is shown under the one to add, so a typo can be compared. The page updates by itself as records are found, and shows the same when it is opened again.
The records can be added in any order. Each check now looks at every record and What is missing lists every problem. Before, it named only the first, and a record added before the ownership record was not checked until the ownership record was found.
