I should start charging you a beer for each of these answers :-)

You may find the following piece of code an interesting addition to your
arsenal of tools when playing with OI.  This piece of code will traverse
a given object hierarchy and print out the names of all objects (properly
indented -- well for vi users :-), you emacs type will just have to cope)
in its path.  Feed it a pointer to your top level app_window and it'll
print out the full application window tree....
