The tabbed docks are useful in collapsing a lot of individual icons into a smaller organized space.  However if a user has several tabbed docks for seldom used programs it can be slightly inconvenient to examine which one is needed each time.  If an optional title was added the user could quickly identify the dock needed at a single glance (this would be similar to Fences, but with the tabbed docks instead of individual icons).

So I would have different tabbed docks for utilities, photography, financial, engineering, etc., and they would be named for quick recognition.
