Submission confirmation
Having a submission confirmation page with all the content seemed confusing to at least one of our testers. Does this show up only in admin view or also for submitters?
Because the content on the confirmation page is formatted differently than on the Preview page, the tester assumed it was new content. She also realised immediately that it was too late to change it, so it wasn't reassuring to see it again.
I recommend just having a standard thank you confirmation modal, without the repeat of the submission details, since those have already been checked.
