Great, thanks for the helpful explanation!  It's pretty obvious what I'm
doing now isn't working, so I'm in for an overhaul one way or another.
 Fortunately, the overhaul is limited to one file out of the project

I'm going to have a run at extending the TreeWalker/TreeWidget code, since I
think it eliminates enough accounting of dealing with expanded/collapsed
nodes and adding/deleting nodes to be valuable.  Moreover, the process of
abstracting that code was a great learning exercise for me, and as a result,
I'm pretty comfortable navigating that chunk of code now.
