Make last modified tickets to stand out

One thing that has come to my mind after a while with RT was making
tickets with newest replies/comments to stand out. In the front page of
RT in the “x highest priority tickets i own” table all of the tickets
titles are balded by default. I would like to change that behavior.
I want that the ticket titles written in plain font, and balded if a
ticket has received a reply that hasn’t been yet read by the owner.
Anyone have any ideas how to do it?

With regards
