I have a quite specific but important issue about creating and printing participants badges from the admin panel.
You have already special fields in the admin for setting up layouts for the invoices. tickets and certificates, which are related to the unique ID of the participant and could be print out, sent by email etc.
May we have a separate field in the admin, dedicated to making badges, where we set up a special layout, add tags from the registrant custom fields and edit if needed. Saved under each registrant ID, with the possibility to print it out.
That would be a great option for all conference organizers, I guess.
