Would it be possible, as a new feature, to be able to enable both the Thank you page AND a redirection after N seconds (configurable) after form submission?

If not possible, to be able to add "buttons" in the Thank you page, instead of links only (for better UI / implicit usage of the "link" as a button)

That would enhance my usecase where users submit forms integrated within my app, and must be redirected in my app after form submission. And I'd need to provide users with some information as part of the thank you page before redirecting them.
