See every field on the page, then fill them all from one popup

Fill or update detected fields straight from the popup, applying saved values back to the page without hopping between tabs.
Surfaces fields that are not visible on the page, which is useful for auditing what a form is really collecting behind the scenes.
Keeps the original placeholder hints intact, making it clearer what each field expects from you.
