Using Separators?

I'm testing out TrueLaunch Bar, and so far it seems exactly what I need. But I can't figure out how to add a separator to my ToolBar. According to the help menu, I select New/Separator from the pop up menu that appears when I right-click the TrueLaunch Bar. The only options I see are Menu, Shortcut, Recently Accessed, and More Plugins. Is this a limitation of the demo version?

right-click on the button not on the empty space.
