Here is a basic outline of how you can create a WordPress plugin to achieve this:

Plugin Name: Email Template Editor

Plugin Description: A GUI editor for editing email templates with WYSIWYG editors and text replacements.

Plugin Files:

	<?php
	/*
	* Assumes your custom post type is called `sma_members`, and that your category has ID `70`.
	* You'd want to chage this if you reused these.
	*/

	function get_cached_sma_members_tags() {
	$cached_tags = get_transient('sma_members_category_70_tags');

	if (false !== $cached_tags) {

	<?php
	/**
	* Plugin Name: Table Import/Export
	* Description: For internal use only. To access, WP-Admin > Tools > Table Import/Export.
	*/
	function table_import_export_menu(){
	add_submenu_page(
	'tools.php',
	'Table Import/Export',
	'Table Import/Export',

	/**
	* To use, initialise this in your theme's functions.php or a plugin file. Then, in a theme file:
	*
	* if( is_subscriber() ){
	* echo "You subscribe to any product.";
	* } else if( is_subscriber( 'subscription_sku' ){
	* echo "You subscribe to the `subscription_sku` product.";
	* } else {
	* echo "No subscriptions found.";
	* }

	<?php
	/**
	* this is wrong. needs to be custom. isn't. idk. will fix later
	*/

	if ( ! defined( 'ABSPATH' ) ) {
	exit;
	}

	do_action( 'woocommerce_email_header', $email_heading, $email );

-function YOURPREFIX_remove_default_theme_site_health( $tests ) {
-	unset( $tests['direct']['theme_version'] );
-	return $tests;
-}
-add_filter( 'site_status_tests', 'YOURPREFIX_remove_default_theme_site_health' );

	let clbData = [{
	"width": clbAttrs.highresWidth,
	"height": clbAttrs.highresHeight,
	"low_res": clbElement.src, // My trigger is the image element so I can take the existing src that is currently being displayed. This is quite good for performance because I know that version is already loaded in. If you make the trigger anything else, you'll need to find another way to provide the low resolution version, it's not optional.
	"high_res": clbAttrs.highres
