It depends which I intended to see.  If I wanted to explore, I'd be 
annoyed at going though inspect, and vice-versa.

Credit where credit is due, Bob's contribution here is a substantial 
one.  However, it hasn't supplanted the inspector; and wouldn't be my 
choice ever (because of the windowing problem) when in MVC.

>OTOH, the cmd-shift-I sounds good, too.

Clearly the better of the two possibilities, IMHO.  If we do that, 
perhaps we ought to rename it the "hierarchical inspector, so they 
both have an "i" therein?
