Microsoft Dynamics GP allows us to add additional menus to its native windows. When we do so, our menu items appear under the heading of Additional. The Additional menu selection will appear at the top of the window along with the standard File, Edit and Help menus.

Prior to Dynamics v.10, the menu name was Extras instead of Additional. The Extras menu appeared at the top of the main Dynamics (or Great Plains) window along with the standard File, Edit and Help menus.
