This is more of a QoL than it is a necessity as you can get the same results by creating a note manually, but the problem is that it can be forgotten.
It would be great if you could add the “Create new note” as an option when you’re closing a ticket or rather just a comment field that when filled in will create a new note in the ticket.
Should be possible to choose if it’s obligatory or not.
In example one could use this field to write how/why the ticket is closed and finished.
