*
* <ul>
* <li>All of the Plot Views that have been activated and registered themselves
* PlotWindowManager
* <li>All views in the view registry whose ID starts with {@link IPlotWindowManager#ID}
* <li>All the view references whose primary ID is {@link

* <li>All Gui Names from {@link PlotService#getGuiNames()}. These are suffixed with {@link

* <li>A <code>null</code> value for a option to open a new unique view name.
