If one or more area features with separate islands/holes within them are selected, the Create Single Vertex List Area From Selected Area(s) With Islands option will appear in the Advanced Feature Creation sub-menu of the right-click menu. When selected, this option will connect all of the islands/holes within the selected parent areas into a single vertex list and replace the original parent/island area with a new area that contains just that single vertex list. This is useful for converting areas with islands into a form that software that cannot handle areas with holes can make use of.
