Dear P&E Teams: We'd love to have branding included for Public Workflows, both in the launch form and in the email notification that goes to the signer. [Having the option to disable the launch email is another feature request for this example.] This is already possible in Counterparty Launch Forms and appears at the top of Custom Emails.
More generally, the ability to have branding options in a given workflow would be great too. This could look like a field in Workflow Designer to upload an image to be used as that workflow's logo where applicable.
