Toolbar

The hierarchies toolbar contains the following:

      Add: invocation of this option adds a new hierarchy to the bottom of the hierarchies list.  The new hierarchy’s default name is 'New Hierarchy'.  If 'New Hierarchy' already exists, it is named 'New Hierarchy 2' (note that this number can be incremented if required).  The new hierarchy is selected automatically and its default structure displayed in the hierarchy details panel:

Top Level Node

§ Node

§ Node 2

Remove: invocation of this option removes the selected hierarchy from the hierarchies list.  It is protected by an 'Are you sure?' dialog.

Toggle View Mode: if the hierarchy structure displayed in the hierarchy details panel is shown in hierarchy mode, invocation of this option switches display to treeview mode.  If the hierarchy structure is displayed in treeview mode, invocation switches its display to hierarchy mode.
