There were some issues with first release of the plugin. Jennifer addressed them all in this new release... and more.
Now you can strip page link entirely ( by creating custom field delink with value true ) or replace it with <a href="#">page title</a> ( by creating custom field delink with value href ).
Important: be aware that first option ( stripping ) might mess up navigation menu on some themes ( horizontal list of parent pages with vertical submenus of child pages ). If this is your case, you can still use second option ( link to "#" ) safely.
