I would like to see the ability to have separate emails based upon the shipping method selection, so if (for example) a customer selected local pickup, I should have the ability to change the email text.

Additionally, I would like to have the ability to edit ALL of the text within each WooCommerce email template and not just have "sections". I feel that a lot of users would like to edit their own messages completely and it would be great if you could support this feature instead of copying/editing PHP email templates and manually having to update each site when you upgrade your system...it just isn't convenient for developers (especially those who build hundreds of WooCommerce Stores) and it's definitely not convenient for store managers.
