WP Favorite Posts 1.4.1 released. See Changelog for differences.

The important change is that;

I’ve added two action; wpfp_after_add and wpfp_after_remove. You can use these actions if you want to do something after someone add/remove a post to favorite. Usage example;
add_action(‘wpfp_after_add’, ‘my_custom_function’);
function my_custom_function() {
// do something
}
