The core Design Palette plugin re-loads all the available settings to match the default Genesis style and layout. The child theme add-ons modify these defaults to match the changes related to that child theme. This filter allows you to change those values for the existing options or to set defaults for any new options added.

Load new defaults for specific keys

function my_new_defaults( $defaults ) {
	$defaults['my-custom-key'] = 'my-custom-value';
	return $defaults;
add_filter( 'gppro_set_defaults', 'my_new_defaults' );
