Feature
Publish and share
Publish a numbered version and share one link or a QR code.
Publishing freezes the draft as a numbered version. People already part-way through keep the version they started, so an edit never breaks an answer in progress.
Copy the public link or scan its QR code. Set a completion cap and the form closes itself when it is reached; closed and paused forms show respondents their own screen.
Duplicate a form to start the next one, and archive forms you no longer need.
