How to get “Widget Logic” plugin’s input value in a custom widget code (to display on the Widget admin page)

I’m almost sure there is no way to do that (server side) without hacking core files, bu luckly i know a little jQuery and i’ve come up with this hackish function that does the job just fine:

function widget_logic_hack(){ 
global $pagenow;
if ($pagenow == 'widgets.php'){
    ?>
    <script>
    function hack_logic(){
     jQuery('input[id$="widget_logic"]').each(function()
        {       
                if (jQuery(this).val().length === 0){}else{
                    var id = this.id;
                    var value = jQuery(this).val();
                    //alert(value);
                    id = id.replace('-widget_logic','');
                    var currenttitle = jQuery("[id$='"+ id +"']").find('h4').html();
                    if (currenttitle.indexOf('Displayed on:') !=-1 ){
                        var ncurrenttitle = currenttitle.substring(0,(currenttitle.indexOf('Displayed on:')));
                        //alert(ncurrenttitle);
                         jQuery("[id$='"+ id +"']").find('h4').html(ncurrenttitle + 'Displayed on: <span class="in-widget-title">' + value + '</span>');
                    }else{
                        jQuery("[id$='"+ id +"']").find('h4').html(currenttitle + '<br /> Displayed on: <span class="in-widget-title">' + value + '</span>');
                    }
                }
        });
    }
    jQuery(document).ready(function(){
        setTimeout("hack_logic()",500);
        jQuery('#savewidget').live('click', function() {
             setTimeout("hack_logic()",5500);
             return true;
        });
    });
    </script>
    <style>.widget .widget-top {height: 40px !important;}</style>
    <?php
}

}

add_action('admin_footer','widget_logic_hack');
