How do I change the form heading

To change the heading of the Testimonials Premium form submission, you need to use a filter in your theme's `functions.php` file. A simple example follows.

add_filter( 'testimonials_widget_premium_form_heading', 'my_testimonials_widget_premium_form_heading', 10, 2 );
function my_testimonials_widget_premium_form_heading( $heading, $post_id ) {
// $heading is the current heading to use like "Add a testimonial" or "Edit testimonial"
$heading = 'Leave a Suggestion';
return $heading;
