Idea: limit

Hi, thank you for your work, it is awesome ??

But I have idea..For example I have on frontpage one sticky post over ns featured checkbox. What I want is limiting click on checkbox in admin custom post types. If I click on my sticky post, others checkboxes will be darken and ajax call not fire – and simple alert in js “News is limiting to 1 item on frontpage”. Some filter for example:

apply_filters( 'ns_featured_posts_limit', function($post_type,$limit) {
    if ($post_type=='news') {
         $limit = 1;
    }
    return $limit;
}); 

apply_filters( 'ns_featured_posts_alert', function($post_type,$alert) {
    if ($post_type=='news') {
         $alert = "News is limiting to %d item on frontpage";
    }
    return $alert;
});
