Breadcrumb NavXT Settings & Post Hierarchy

Using the bcn_post_terms filter, you can return just the first term (in an array). Something like the following should work:

add_filter('bcn_post_terms','my_bcn_post_term_selector', 10, 3);
function my_bcn_post_term_selector($terms, $taxonomy, $id)
{
	//Check to ensure the terms list is an array and there is more than one item in it
	if(is_array($terms) && count($terms) > 1)
	{
		//Return the fist item in a new array
		return array(0 => reset($terms));
	}
	return $terms;
}

This code was taken from an article on bcn_post_terms that scheduled for release on May 15th.
