The Favorites menu is a bit dull and hard to read since it only shows the final actual menu link. Many of the menu items in the site menu are named in a way to correspond to the parent second tier menu. I.E. Invoices in the Sales Order menu segment makes sense, but you'd never know it to see it simply in the favorites bar.
For both looks and convenience, if there is more than one menu item from the second tier menu in the favorites list, categorize it by the title of the second tier menu. See attached rough screen shot
