 ~Diminished modes are minor modes with no modeline display~
    Diminish is used to hide modes from the mode bar in emacs. It's also required to use the diminish function in =use-package=

    #+BEGIN_SRC emacs-lisp
(use-package diminish)
    #+END_SRC

    Vim keybindings for emacs to get the best of both worlds.

    #+BEGIN_SRC emacs-lisp
(use-package evil
  :init
  (setq evil-want-keybinding nil)
  :config
  (evil-mode 1)
  (setq evil-search-module 'evil-search))

(use-package evil-collection

  (evil-collection-init))
    #+END_SRC

*** Ivy/Counsil/Swiper

    Simply a interface for completion/search in emacs.

    #+BEGIN_SRC emacs-lisp
(use-package prescient)

(use-package ivy-prescient

** Transparent Emacs
   Makes the default color of the background of emacs the same as the terminals color. 
   This is kind of a janky solution, but it works.
   It doesn't work when you reload the config manually while emacs is running.

(add-hook 'window-setup-hook
      '(lambda ()
	 (set-face-background 'default "unspecified-bg")))

* Org Mode
  Always unfold every section in org files.

  #+BEGIN_SRC emacs-lisp
(add-hook 'org-mode-hook #'org-show-all)
(add-hook 'org-mode-hook (lambda () (org-bullets-mode 1)))
  #+END_SRC
