    (add-to-list 'default-frame-alist '(height . 40))
    (add-to-list 'initial-frame-alist '(width . 80))
    (add-to-list 'initial-frame-alist '(height . 40)))

run the function at startup of a frame

  ;;     (ligature-set-ligatures 't '("www"))
  ;;     ;; Enable traditional ligature support in eww-mode, if the
  ;;     ;; `variable-pitch' face supports it
  ;;     (ligature-set-ligatures 'eww-mode '("ff" "fi" "ffi"))
  ;;     ;; Enable all ligatures in programming modes

  ;;     (global-ligature-mode t)))

Theme

Load theme (that is built-in)

  (load-theme 'modus-vivendi t)

Line numbers

Turn on line numbers in text mode/code modes.

  (add-hook 'term-mode-hook (lambda () (display-line-numbers-mode -1)))
  (add-hook 'text-mode-hook 'display-line-numbers-mode)
  (add-hook 'emacs-lisp-mode-hook 'display-line-numbers-mode)
  (add-hook 'prog-mode-hook 'display-line-numbers-mode)

Welcome Screen

Having a blank screen at the start is much more simpler and better

  (setq inhibit-startup-screen t)
