Quicklist not supported on Unity2D

Binary package hint: unity

For example, Banshee on Unity3D has controls on the quicklist, other apps have menus, etc...
But on Unity2D there's no quicklist :/
Like this http://www.omgubuntu.co.uk/wp-content/uploads/2011/04/Screenshot-r90-r85_thumb.jpg
I attach the Banshee screenshot
