Clearsigning is particularly useful because it lets me CC others (they see the command language, have an opportunity to learn it, question my action---the social setting of e-mail works very well for interaction with this sort of command language). I suppose I could just clearsign a region of a text e-mail, but (a) that means I need an even more complex UI on mobile devices, and (b) I don't trust my mail chain not to screw up the formatting---which is part of why we have PGP/MIME in the first place. The next-best alternative is a web interface, but that removes the ability to manage it through mail---with all the threading and conversation conventions that come with it. I'm also curious about the UI: do you expect to only offer (encrypted+signed) and (plaintext)? If there are separate toggles for encryption and signature anyway, what's the UI benefit? -Brian
