Add new filter for return URL in Customizer

[rabmalin]

Since 4.4 return URL in Customizer is managed from get_return_url() [class-wp-customize-manager.php]. I wanted to override that return URL but I could not find filter. It would be great if we could add a filter for the URL.

@rabmalin You can accomplish this via:

<?php
add_action( 'customize_controls_init', function() {
        global $wp_customize;
        $my_custom_return_url = '...';
        $wp_customize->set_return_url( $my_custom_return_url );
} );
