generate_header_items() has been simplified so you can easily change the order or elements in the header

gistfile1.txt

if ( ! function_exists( 'generate_header_items' ) ) :
/**
 * Build the header
 *
 * Wrapping this into a function allows us to customize the order
 *
 * @since 1.2.9.7
 */
function generate_header_items() 
{
	// Header widget
	generate_construct_header_widget();
	
	// Site title and tagline
	generate_construct_site_title();
	
	// Site logo
	generate_construct_logo();
}
endif;

Where is the 'generate_header_items' function located? I am trying to add two more images to the header via a function.

In wp-content/themes/generatepress/inc/template-tags.php

Now in wp-content/themes/generatepress/inc/structure/header.php
