"Tickets in my court"?

Is there a visual way for an engineer using RT to distinguish between tickets
that have been replied to by the customer.
I am looking for a visual way rather then an email notification from RT.
(would be nice to see a little ‘**’ preceding each such ticket for example)

Tips? Suggestions?

BTW - we have both RT2 running and RT3 tested we are targeting the production
based on RT3, Love it!!
