The following image shows the way Gmail represents a long thread of emails between two persons with the same object. You can see the headers and not the text of the single emails.
This kind of emails are functionally identical to a chat. There is no need for an object, there is no need for an header, just seeing the author and the text of the emails would be enough. It's just me and another person. Every message consist of few lines. And there are tons of messages. Google Wave was doing something good in this sense.
Can I visualize this thread of emails as if they were messages in a Facebook Chat
Me: blablabla
Him: dsfsdfjsdklfjsdlf
Me: dfasfjklsdjflkdjsf
Him: fhsdjkfhsdf
without any header?
Is there any tool/plugin to do something similar?
