In addition, the user can toggle back and forth the preference. There doesn't seem to be an obvious way to tell the outline controller, "skip or hide this item".
See -[NSArrayController filterPredicate].
If that doesn't suit your needs, subclass NSArrayController and do
your filtering in -arrangeObjects. If *that* doesn't suit your needs,
bind your array controller to a to-many property you control and do
your filtering there.
