Thank you very much for posting your feedback. At this time, we will not be adding this request to the near-term backlog, as we are focused on other advanced features, styling, etc., that is obviously critical and more important. Please keep the feedback coming as it is critical for our longer-term planning.
Just to help me better understand your request - Are you looking at validation messages on the public-facing web form? So similarly to your "Success Information - Form sent" suggestion, you'd like all Form messages/errors to be translated?
