We'd love to see the ability to reference field input within text blocks, labels, the confirmation message and all aspects of the email notifications. If a user provides their name, they should expect to see their name referenced further down the form, get a personalised thank-you in the confirmation message and receive a personalised email notification.

Further, the subject line of the email notofication must contain a custom reference to the specifics of the completed form via dynamic field references / placeholders...

a) for a clear indication of the email's relevance to the recipient

b) to help filter the incoming form results within owner notifications and avoid them all looking exactly the same in the inbox

c) for an overall improved UX and communication best practice

This behaviour is standard with most of your competitors and would be absolutely vital for the way we'd use your otherwise brilliant form builder system.
