The editor in SDP is terrible. Formatting is very limited, what looks fine in the editing window looks terrible in emails, it seems to randomly add and remove line breaks all over the place.

The feature I would like to see:

Keep the default editor where it is.

Just give me a button to say 'Use this HTML file for this notification'. I don't require a full HTML editor to be embedded into SDP, there are so many better editors out there, but I do need to be able to assign a clean, unaltered, HTML file as a notification.

The HTML file can be loaded into the DB or it can be maintained in the filesystem, it doesn't really matter to me.

That way I can create whatever look I need and be confident that it will survive through to the email client.

I think this should be far easier to implement over a fully functional HTML editor 'in browser'. At the moment I copy/paste my notifications into the Window however the results are poor (at best).
