As shown above, you can add session nodes and catalogues to corpus nodes. Moreover, you
can also add additional elements to session nodes and catalogues. If you right click on a
catalogue > add, you will see a list of items available in the context menu. Notice how some
elements have the icon, whereas others have a icon
. The
icon represents a component that will be displayed in the hierarchy
whereas the
icon adds a
new field (discussed below).
