This seems horribly inefficient to me, I have thousands of items in

Just to say something about this also - the outline view will only ask
for as many items as it needs to actually display. So it need not be
inefficient unless you design it badly. So, with a sensible design,
worst case you're only going to have a few dozen wrapper objects in
existence at once, and best case, just one - the one that the outline
view is drawing right now. The outline view does not cache its data
content in any way, as far as I know.
