It only took me three weeks to get back to this issue... darn work is 
getting in the way of my playing around with tile! :-)

Yes, I agree that [$nb identify $x $y] seems like the right solution. It 
could, for instance, return "image 0" if you click on the image for tab 
0, "tab 0" if you click on any other part of the tab, "trough" if you 
click in the trough (unoccupied area where tabs appear).

I'd like to suggest something like this:

     ttk::button .nb.dismiss ....
     .nb addwidget .nb.dismiss

This would let you add widgets to appear in the trough. They would 
appear right-aligned, and you could potentially add more than one. 
Normally you'd just add buttons, but labels or progressbars might be 
other choices. This could easily be abused to put all kind of cruft in 
there, but hopefully most people would limit themselves to a bare 
minimum (read: firefox-like "close the current tab" button)
