tinyNav & default header text…

Hi there, On Catch Box, the tinyNav mobile device menu, I've looked at the catchbox-menu.js ( un minified ) and see there is an option "'header' : false // Boolean: Show header instead of the active item" I want to change the menu from having the active item ( page name ) to have the default "Navigation" text... changing to "true" doesn't in itself change the menu to display the default "Navigation" text... what else needs to happen for this to work? Thanks.
