When I have replied to or forwarded a message TB displays a nice arrow in the appropriate column. But how can I find out when I replied to or forwarded it? And to whom I forwarded the message? Yes, I know, I can try and look the message up in my "Sent" folder. (Good luck if I changed the subject and forwarded it six weeks later...) But that is way too clumsy and slow. Clicking on the arrow (or hovering over it) to display that information would be nice. :) The only workaround I have found is to view it as a thread tree. But that is still not really user-friendly... Anyone?
