Hi Jens,
[...]
The header line is most problematic in my case (and maybe others) as I use the very cool tabbar.el by David Ponce (which is unexplainable to me still not part of standard emacs...) - So putting something there exclusively doesn't work for me.
[...]
FYI, you can use tabbar-local-mode to temporarily show/hide the tab bar when the header line is currently in use with the current buffer. This is useful, for example, in info mode, or when ruler mode, or semantic stickyfunc mode is enabled. tabbar-local-mode is particularly useful if assigned a keyboard shortcut. My personal choice is:
(global-set-key [(control f10)] 'tabbar-local-mode)
Sincerely, David
