** Modeline cleanup
Adds support for =:diminish= in use-package declarations,
basically hides a mode from the modeline.
#+BEGIN_SRC emacs-lisp

** Keybind completion
Pops up a buffer that helps you navigate and complete commands

** Keybind Manager
General manages my keybindings.

#+BEGIN_SRC emacs-lisp

*** Leader definitions
Create a leader key, like the \ in vim.
In this case, =SPC= is used as a leader. Following the leader,
different buttons bring you to different options.
