I found there are configuration like this:
#+begin_src emacs-lisp ;;; display org-clock in head-line. (setq org-clock-clocked-in-display nil) (defun my/show-org-clock-in-header-line () (setq-default header-line-format '((" " org-mode-line-string " ")))) (defun my/remove-org-clock-in-header-line () (setq-default header-line-format nil)) (add-hook 'org-clock-in-hook #'my/show-org-clock-in-header-line) (add-hook 'org-clock-out-hook #'my/remove-org-clock-in-header-line) (add-hook 'org-clock-cancel-hook #'my/remove-org-clock-in-header-line) #+end_src But this header-line is displayed in every window. I wish there is a global header-line to display org-clock info. Why I want this? Because my notebook screen is small, when I split window, the mode-line is very small not enough to display much info for org-clock. I don't want to display org-clock info in frame-title. That's not the right place. I saw some Emacs extensions like tabs package (for example: nerdtab https://github.com/casouri/nerdtab) display a global top line instead of per-window. -- [ stardiviner ] I try to make every word tell the meaning what I want to express.
