Great, i can see even 'copy' button. I thought that raw view will insert header into email itself. Then i could copy only infromation i am interested in, not the whole header. On the mobile it is hard to edit whole header to select only e.g. IP or other info to note app.
I think that it is great header view within email list, but from message i think it has to be just like the ithers do: simply show whole message in raw format, just like it is: HEADER, 2xnew lines, MESSAGE.
