Very good!!
Please allow me to support this request.
I am setting up MailPoet on a sandbox site and, to be able to do the setup again on a production site without accidentally missing something, I now maintain a detailed list with actions. This is currently two MS Word pages with small print, NOT including the exact layout and contents of new WP-pages, forms, templates, and some additional php, css and js code.
Of course I will export and import the email templates and re-use the additional code, but that is not the point. It would really be great if you can export and import/transfer, as much as possible, the MailPoet installation itself.
