We have a significant number of forms that require address input. In terms of UX, we'd really like to be able to offer an address autocomplete to save the user having to jump through half a dozen fields to fully complete their address.
This also allows us to capture cleaner and more consistent address data, which can be a significant challenge for Council.
I think rather than implementing a potentially difficult address lookup, a generic ability to invoke a REST call to return autocomplete data, then map that into various standard form fields would be awesome, and reusable across a number of use cases.
We'd be super keen to see something like this!
