As a ticketing system, it is essential to enable admins to mange tickets and registration for their events:
1. Remove / cancel a ticket
2. Approve a pending request
3. Add tickets or people manually
4. Increase seats
5. Waitlisting options (Create waitlist seats quota, Move to waitlist, approve into event etc.)
Currently, none of the features above exist and it makes it almost impossible to manage ticketing & registration in an elegant way.
