[Feature Request] Keep old input on resubmit

[rootsh0pf]

Imagine a user fills a form and submits it. A moment later they realise that they filled something wrongly. When they click the link again and then use the "resubmit" function, it would be cool if there would be an option to prefill all fields again with the information entered before. Like this they would only have to change the small wrong part and not fill the entire form again.

Btw: Thank you so much for this amazing project!
