Do not download if you already updated your email templates.

I’m currently working on my email template and started to edit Woocommerce emails. I changed all of the layouts of my emails. It is almost complete except for the text then I found this plugin. Tried to install and activate but it doesn’t inform me that my current tempalte will be overridden. All of my hardwork to edit the layout is gone without any backup created by this plugin. What a total mess.
