Thunderbird Folder name in Reading window title

Hi Folks:

Thunderbird is a lifesaver!  I have used Netscape for my email client 
for years, and it quit working.  Thunderbird took over flawlessly!  
Thanks to all of you who contribute.

I use Microsoft Windows, currently XP Professional.  I believe the 
behavior is the same on Vista.

A suggestion.  When I am looking through my Folders, the name of the 
folder appears in the window title.  But, when I am reading a message, 
the Folder name is not displayed.  It would be really helpful to me if 
the Folder name could appear in the window title when reading, as well.  
My reason is that I use rules to move messages, and my disposition 
(delete, file or just next) depends on which Folder the message is 
currently in, that I am reading from.

If this feature is already available, with some option settings or 
registry values, please let me know.

Thanks for the consideration.
