I suggest adding a Form Submissions card to the right sidebar in Contacts. Currently, we show the From submission activity in the contact timeline. And there are some contact properties that mention ‘conversion’ (form submission) but we do not yet have a Form Submission card along the right side. If added, it would fit nicely along with existing cards like List Memberships and Workflows. It would be great to quickly see which forms a contact submitted.
