Post and close

Would be great thing to have the option when posting a reply to a ticket so have the option to ‘post and….’
… mark as solved
… mark as closed
… mark as on hold

We find currently that when we are about to close a ticket, we end up with two emails gong out.
One to say we have fixed it and will now close the ticket, and one following when we close it.

It would be awesome if and option to post and close the ticket might add the final comment to the ticket closed email.
