It is not clear to me that information is best put in the status bar and 
not the title bar (which is where Unix-like systems can put it, and even 
where Explorer does, and can be seen in the minimized versions).  So I 
would think setWindowTitle() was at least as appropriate (and so did the 
person who wrote its examples).

Yes, that has been proposed recently in connection with interfaces for 
messages().  Note though that at present only the MDI interface has the 
option of a status bar.  I think we should move to a more standard way of 
having these 'toolbars' on or off (e.g. ticked items on a View menu).
