Aha, I just made it work. Looks like the default is more horizontal.
If you de-select "HORIZONTAL_TREE" in the Preferences window and then click
Done or Save, nothing at all seems to happen in the current xace session.
(Should it?) However if you click Save and start a new xace session, you'll
see what more vertical looks like.
I don't think either of these is as good as the 4_3-style tabbed layout, but
it could be a matter of preference.
