A very interesting project and nicely timed too since the protection
of header data will very neatly address a major concern which is now
relevant in Australia with the passing of mandatory data retention
legislation. Yeah, now officially a police state, within 18 months
everyone will be under constant surveillance.
The custom and single client, as MFPA pointed out, might be
contentious for some users, but there are reasons and clear benefits
too. I think the major features I'd request would be:
* The ability to load a new message or reply in the editor of your
choice from the client when drafting, which ought to cut down on a
lot of the UI debate.
* A client API so that people can extend it further the way they want,
effectively creating multiple clients from the required base.
After that, the rest will attend to itself.
