Magento 2 Custom variables HTML Editor

Overview

Custom Variables are a handy little feature Magento 2. Magento allows you to create custom variables and then use them in e-mail templates, the WYSIWYG editor, or even code expressions. These are particularly useful when creating re-usable content across the store. The custom variables themselves are managed in System -> Other settings -> Custom variables and while stuff seems easy at first, there is a cumbersome process of managing HTML content through plain textarea. We have addressed this issue with this little extension for Magento 2.x. It adds WYSIWYG editor to Variable HTML Value in Custom Variables allowing for more user-friendly and robust content management.
