Page/Parent name in Spoiler Title

Using WP UI Manuel Widget in sidebar to show 2 spoilers at https://perryfamilyroots.com. One for child pages of current page; one for sibling pages but wanted to show the page name in the spoiler title instead of just saying “child pages” and “sibling pages” since this is a genealogy site and those words might lead users to think it referred to children and siblings of the ancestor the page was about. I’m not a PHP programer and it took a while to figure it out but finally did.
Added just 5 lines to wp-ui.php. Only problem will have to make the changes again when next upgrade occurs. Any one know a way to do this outside of wp-ui.php? Don’t know if anyone else would want to use it but maybe Kav could just added it to the next upgrade
This is what the change looks like:

function sc_wpspoiler( $atts, $content = null ) {
// I ADDED THESE 3 LINES
$currentpage = get_post();
$thispage = $currentpage->post_title;
$thispageparent = get_the_title($currentpage->post_parent);

		extract( shortcode_atts( array(
				'name'		=>	'Show Content',
				'_id'		=>	false,
				'style'		=>	$this->options['tab_scheme'],
				'fade'		=>	'true',
				'slide'		=>	'true',
				'speed'		=>	false,
				'closebtn'	=>	false,
				'showtext'	=>	false,
				'hidetext'	=>	false,
				'open'		=>	'false',
				'post'		=>	'',
				'page'		=>	'',
				'elength'	=>	$this->options['excerpt_length'],
				'before_post'	=>	'',
				'after_post'	=>	'',
				'template'	=>	'2',
				'background'=>	'true'
			), $atts));

// AND THESE 2 LINES
		$name = str_ireplace( '{$thispageparent}', $thispageparent, $name );
		$name = str_ireplace( '{$thispage}', $thispage, $name );

And then used “$thispage} section contents:” and “Also in the {$thispageparent} section:” as titles for the spoilers.
You can see the results here.
NOTE: I originally had all 5 lines where the bottom 2 are but for a reason i don’t understand $thispageparent was being set to the current page title, not it’s parent. Moving the first 3 lines to their current position fixed that problem.
