Draws per-frame mode-line and/or header-line and allow to customize per-window header/mode-line.
git clone git@github.com:Bad-ptr/common-header-mode-line.el.git
cd common-header-mode-line.el
make package
This will create a tar file in the common-header-mode-line.el/pkg/ directory.
Or you can download a release.
Then start emacs and M-x package-install-file RET path/to/common-header-mode-line-{version}.tar RET.
Put the following into your emacs config:
(with-eval-after-load "common-header-mode-line-autoloads"
(common-mode-line-mode 1)
(common-header-line-mode 1))
M-x customize-group RET common-header-mode-line RET
M-x customize-group RET common-mode-line RET
M-x customize-group RET common-header-line RET
M-x customize-group RET per-window-header-mode-line RET
M-x customize-group RET per-window-mode-line RET
M-x customize-group RET per-window-header-line RET
M-x customize-group RET per-frame-header-mode-line RET
M-x customize-group RET per-frame-mode-line RET
M-x customize-group RET per-frame-header-line RET
Activating the common-header-mode-line-mode is equivalent to activating
common-header-line-mode and common-mode-line-mode which is equivalent to
activating per-frame-header-mode-line-mode and per-window-header-mode-line-mode
which is equivalent to activating per-frame-header-line-mode, per-frame-mode-line-mode,
per-window-header-line-mode and per-window-mode-line-mode.
You can enable/disable any subset of these minor-modes at any time.
For example you can enable the common-header-mode-line-mode and then disable the per-frame-header-line-mode:
(common-header-mode-line-mode 1)
(per-frame-header-line-mode -1)

Result of the above code:
Edit a *-source.el, then run make package, install package,
then start emacs, activate the common-header-mode-line-mode,
test how it works, if works well commit and push.
When editing *-source.el using $* in symbol or string will
cause the current top level form be repeated two times
-- first time the $* will be replaced by header, second time by mode.
The $@ in symbol or string will be replaced by header-mode.
$0 -- to header, $1 -- mode.
($eval expr) is replaced by the result of evaluation of the expr.
($subloop expr) limit bounds of the $* expansion.
