Page Header page name

You can always add it manually, but you're trying to add it automatically, correct?

Yes.
There's a way that calling the function "generate_page_header_area" on my theme and then I echo the "the_title();" ? Maybe a hook do that, right?

Hmm, well the page header area will only show if some sort of content/image is added to the metabox.

You could try something like this (untested):

add_action('generate_after_header','generate_add_title_below_header');
function generate_add_title_below_header()
{ 
	// If we're not on a page, don't do anything
	if ( ! is_page() )
		return;
	?>
	<div class="page-header-content generate-page-header generate-content-header">
		<div class="inside-page-header-container inside-content-header grid-container grid-parent">
			<?php the_title(); ?>
		</div>
	</div>
	<?php 
}

You can add that snippet using a plugin like this: https://wordpress.org/plugins/code-snippets/

Let me know - it may need some tweaking :)

That's it! Sometimes I forget the use of GP Hooks!
One last question, if I want to do the same to posts? And only exclude the homepage?

Thank you so much for your time Tom! And again, awesome job with the GP!

Then I would change the code to this:

add_action('generate_after_header','generate_add_title_below_header');
function generate_add_title_below_header()
{ 
	// If we're not on a page, don't do anything
	if ( is_page() || is_single() ) {
	?>
	<div class="page-header-content generate-page-header generate-content-header">
		<div class="inside-page-header-container inside-content-header grid-container grid-parent">
			<?php the_title(); ?>
		</div>
	</div>
	<?php }
}

Thank you once again Tom!

You're welcome :)
