** Theme
Use the Modus Operandi theme by Protesilaos Stavrou. Its the best theme for Emacs by far, because how clear and readable it is. It is highly customizable, but I just set a few options here.
#+begin_src emacs-lisp
- (setq modus-themes-slanted-constructs t
- modus-themes-bold-constructs t
- modus-themes-mode-line '3d
- modus-themes-scale-headings t
- modus-themes-diffs 'desaturated)
- (load-theme 'modus-vivendi t)
+ (use-package modus-themes
+ :custom
+ (modus-themes-slanted-constructs t)
+ (modus-themes-bold-constructs t)
+ (modus-themes-mode-line '3d)
+ (modus-themes-scale-headings t)
+ (modus-themes-diffs 'desaturated)
+ :config (load-theme 'modus-vivendi t))
