duplicate-theme

It does exactly what should do. Clone / Copy theme to avoid problems from future original theme update before checking them. I remembered this plugin from some time ago, but I wasn't able to find it here by searching in plugin directory. I found it again thanks some article about this. Great work and thank you again

While your plugin does successfully create a "child theme", it seems to DUPLICATE *every* directory and file from the parent, instead of merely creating a new STYLE.CSS in the child's root directory with one simple reference to utilize the parent theme's STYLE.CSS. My point / concern is, especially for those who may be unfamiliar, that the intrinsic behaviour of WordPress is to first utilize files that exist in the CHILD theme directory .. regardless of the same filename existing in the Parent theme directory. Hence, once a Theme core/parent gets updated, one's WordPress site will continue to only load the now-antiquated files in the Child -- files that were copied at an earlier timeframe using this plugin. In summary, once a Child theme is created using this plugin, all future updates to the theme's parent will be ignored. Proof is in this article: https://wordpress.org/support/topic/child-themes-and-php-pages

This is a great plugin for child themes!
