Hi!
Thank you very much for your kind words.
1. Unfortunately this is not possible, the plugin can only access the local database.
2. Sure! You can either use a widget, that is visible sitewide, or you can also use a custom code with the plugin shortcode.
Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
add_action('wp_footer', 'asp_print_search_footer');
function asp_print_search_footer() {
echo do_shortcode('[wd_asp id=1']);
}Make sure to have the correct shortcode within the do_shortcode function call on line 3.
