Frequently enough that I write this post, it is required to send 'full headers' when I forward a message. Currently I hit Forward and write my content above the forwarded email. But the actual process is:
View|Headers|All then click Forward, enter my message and hit SEND.
BUT then I have to View|Headers|Normal to continue reading other email and responding some times forwarding without the headers sometimes with depending on the situation. Having a Forward w/ headers Forward w/o headers choice would be awesome time saver. Alternately a button to toggle headers All/Normal somewhere on the view pane would work as well.
