That's an interesting, and non-trivial, suggestion. I would love to see mail clients try to figure out, given several raw messages, what the flow of the conversation/thread is like, then offer a canonical representation of that conversation, with perhaps a focus on what a single message contributed to the whole. Or one of several representations, among which the user chooses. That would be quite neat - but like I said, it's not at all easy
