On a domain's DNS page, Add record saves the record and closes the form, and the new record appears in DNS records without the page reloading. Add and add another keeps the form open, cleared for the next record with the same type and TTL. If a record cannot be saved, the form stays open with what you typed and says why. Record details saves the same way.
Adding a DNS record no longer reloads the page
Add record and Add and add another on a domain's DNS page now save without reloading, and the record appears in the list at once.
