I send a suggestion that I hope will be accepted.
Today the To address of e-mail notifications it's always the email address set up in the Joomla! user's profile for the recipient. Depending on the email type the recipient may be either the user who owns the ticket or one of the users who are designated as support staff (they have the core Manage privilege for ATS).
Could you add the ability to add additional CC addresses for each client profile or for a specific ticket?
Thank you
