Updated tickets only

My users don’t like the amount of alert email they get, but there is no
other way for the user to see that one of the tickets in one of the
queues has had a reply from a requestor. Many of our tickets go twenty
emails and it’s wasy to miss the replies without the notifications.

Is there any way the user can see a view of all queues that have been
updated since she last looked at the ticket?
