At long last, Power Mode is available for the best text editor.
(It looks way better than in the gif, trust me.)
Currently, this package is not on M?ELPA. In the meantime, please clone and extend your load path. For example:
(use-package power-mode
:load-path "site-lisp/power-mode.el"
:init
(add-hook 'after-init-hook #'power-mode))
