Referring back to this thread: Toolbar STATE=Center and Folder Toolbar Conflict
Request a new state - call it dcenter, for example - be added that
(1) positions the toolbar in the center of a dual-display lister,
(2) maintains its position to the right of a single-display lister should the dual-display be closed, and
(3) stays to the left of the Metadata and/or Viewer pane when only a single-display lister is open
