I still managed to miss yet another (the 11th) crucial view in Outline
4D. Thanks to its MDI, it's possible to display 2 (or more!) versions of
the same outline side-by-side, so e.g. if you're working on a very large
outline, you can have the top displayed in one, and the bottom in the
other (with changes updated to both).

Or you can have a different type of view applied to each window. In this
example the left window is in full view, the right window is in "titles
only" (skeletal) view. I can't believe I haven't discovered this
sooner...

In fact this option does make it similar to BrainStorm's aerial view, except that you have a lot more options in terms of visualisation of outline for both panes.

If you do this with the timeline view in one pane (with "View > Fit to View" on), and outline pane in the other, you could even emulate Grandview's document window combined with a Brainstorm style aerial view:
