I have been lamenting quietly that it takes too many keystrokes or mouse operations to go from normal header display to full header display. I just discovered, however, that if I select View -> Headers -> All, but then click the [-] button at the top left of the header, I get as default what NS used to call (IIRC) "brief" header display (one line), but a click on the resulting [+] button will show the full header.
