In addition to adding/removing/checking in registrations, I'd like to also include payment options (cash, credit). This would automatically update the outstanding invoice in the system, eliminating the need for a manual edit. The organizer would have a "live" list of registrants at their fingertips and see who has paid and who hasn't, even if they registered an hour before the event - as occurs in often in our club.
