[Plugin: Pronamic Google Maps] route in Balloon

@nashua In the next relase you could the ‘pronamic_google_maps_item_description’ filter to automatically add extra content to the description in the balloon.

function prefix_pgm_item_description($description) {
	$description .= '<a href="#">Route</a>';

	return $description;
}

add_filter('pronamic_google_maps_item_description', 'prefix_pgm_item_description');
