;;; Commentary:
;;
;; Nano modeline is a an alterntive to the GNU/Emacs modeline. It can
;; be displayed at the bottom (mode-line) or at the top (header-line)
;; depending on the nano-modeline-position custom setting. There are
;; several modelines that can be installed on a per-mode basis or as
;; the default one.
;;
;; Usage example:
;;
;; Install prog mode modeline:
;; (add-hook 'prog-mode-hook #'nano-modeline-prog-mode)
;;
;; Make text mode modeline the default:
;; (nano-modeline-text-mode t)
;;
;; Install all available modes:
;; (add-hook 'prog-mode-hook #'nano-modeline-prog-mode)
;; (add-hook 'text-mode-hook #'nano-modeline-text-mode)
;; (add-hook 'org-mode-hook #'nano-modeline-org-mode)
;; (add-hook 'pdf-view-mode-hook #'nano-modeline-pdf-mode)
;; (add-hook 'mu4e-headers-mode-hook #'nano-modeline-mu4e-headers-mode)
;; (add-hook 'mu4e-view-mode-hook #'nano-modeline-mu4e-message-mode)
;; (add-hook 'mu4e-compose-mode-hook #'nano-modeline-mu4e-compose-mode)
;; (add-hook 'elfeed-show-mode-hook #'nano-modeline-elfeed-entry-mode)
;; (add-hook 'elfeed-search-mode-hook #'nano-modeline-elfeed-search-mode)
