I have similar problems when copying the IBAN. In the UI the iban is shown as formated but some websites do not accept the formated version and need the compact version.
I’m wondering if it makes sense to add a “Copy” widget which justs shows an icon like the URL widget and copies the value of the field into de clipboard.
We may go even further by allowing to edit the “Full Address” and use one the parsing library to fill the detail fields. (Maybe this makes sense only for new addresses).
The formatted version of IBAN is to help human to type it without error so requesting the compact version is a UI design mistake.
This won’t help the current topic because the adresse is not a widget but a record composed of multiple widgets.
