Allows theme authors to include templates that will be automatically used based on the page’s parent.
For example, adding the file “page-123.php” to the “child-page-templates” folder in your theme directory will define the template for all pages that are children of the page with ID #123. You can also do the same thing with the post’s slug.
This template file will be used for all pages that are children of the page with ID #123: 
/wp-content/themes/your-awesome-theme/child-page-templates/page-123.php
This template file will be used for all pages that are children of the page with the “team” slug: 
/wp-content/themes/your-awesome-theme/child-page-templates/page-team.php

WordPress themes consist of a variety of templates, which makes customization difficult. 
This plugin allows you to see all the templates used to display the current page. 
Of course, if you are using a child theme, you can also understand the structure of the parent theme as well. 
This plugin can be used to create an environment that is easy to customize when templates are loaded in a complex way and the theme editor does not know what to do with them.
The following basic template is used in WordPress.
functions.php 
header.php 
sidebar.php 
footer.php 
index.php 
page.php 
single.php 
archive.php
In fact, there are various original files included in addition to these, and some themes consist of nearly 200 templates.
From 2.0.2, it is also possible to extract the configuration template loaded from the plugin folder when using WooCommerce.
