It would be great to have html emails working better throughout the admin system. it is currently very basic and rather restricted. with not much work it could be made much much more powerful.
Currently, if you copy/paste a propper complex html designed email into the box on various pages in the admin its then very hard to update the email as the actual copy area is normally way off screen amongst a huge amount of general html.
to solve this it would be great if the wysiwyg interface could be added to all html email options in the admin.
even better would be for the option to support external "email templates". This way, the copy in the box would just be the actual propper email message as it is with a text email. viart could then load the html file from the web server that is to be the base of the html email and then insert the message into a specified part of the html file using some special keyword.
