Thanks, that looks very useful. I only have one trepidation about it, 
which concerns this:

Isn't -arrangedObjects one of those methods you're never supposed to 
call manually, only through bindings? At least, that seems to be the 
vibe I picked up while searching the list before posting my question. 
The docs say this:

which of course is nice and ambiguous. It says no assumption should be 
made, but says that in a paragraph prefixed by "Prior to Mac OS X 
v10.5". Since the root note was opaque and unreliable as to format 
prior to OS X v10.5, does that mean that it *can* be reliably used now 
that it is defined as an (sic) proxy root tree node for the (sic) 
containing the receiver's sorted content objects, or does that still 
apply?

Thanks,
