Great, thanks.

The permanent one in the first line.

None at the moment! I just thought, seeing as the header is used to give
a help message by org-edit-src-code, it might be worth introducing a
mechanism whereby one can choose between two "levels" of help
messages. I didn't mean to give the impression that I had several things
I wanted to change.

I admit this is a personal and mainly aesthetic preference -- once I've
learned how to use it and the relevant key binding, I prefer to have
(the option to have) a screen free from content other than the minimum
necessary (the echo area will still provide the information). I'm
guessing that quite a few org users have dispensed with the emacs menu
bar (and scroll bars), and was thinking that the proposed option might
appeal to those sorts of people.

p.s. I think the docstring in org-edit-src-code needs updating to
reflect the change.
