* Removing evil-mode
See the [[https://github.com/hlissner/doom-emacs/wiki/FAQ#remove-vimevil-for-a-more-vanilla-emacs-experience][corresponding question in the FAQ]].

* Features
+ A better ~:g[lobal]~ command with incremental highlighting.
+ Adds the ~:al[ign]~ ex command: offers an ex interface to ~align-regexp~ with
  incremental highlighting.
+ Support for more of vim's filename modifiers in ex commands (like ~:p~, ~:p:h~
  or ~:t~) than vanilla evil-mode offers.
+ A list of new text objects:
  + Blocks: ~B~ (from ~evil-textobj-anyblock~)
  + Args: ~a~ (from ~evil-args~)
  + Indentation: ~i~ / ~I~ / ~J~ (from ~evil-indent-plus~)
+ Incorporates vim functionality ported to evil:
  + ~vim-commentary~ => ~evil-commentary~
  + ~vim-easymotion~ => ~evil-easymotion~
  + ~vim-multiedit~ => ~evil-multiedit~
  + ~vim-multiple-cursors~ => ~evil-mc~ & ~evil-multiedit~
  + ~vim-seek~ or ~vim-sneak~ => ~evil-snipe~
  + ~vim-surround~ => ~evil-embrace~ & ~evil-surround~
+ =NERDTree= equivalent is available in =:tools neotree=

** Multiple-cursors
Two multiple-cursor implementations exist in this module: ~evil-mc~ and
~evil-multiedit~. Together, these provide the functionality of
~vim-multiple-cursors~.

The former lets you place "clone" cursors. The latter lets you interactively
edit many regions at once (like an interactive version of ~:%s~).

** A hybrid code-folding system
This module combines ~evil-vimish-fold~ and ~hideshow~. The former allows
arbitrary folds and the latter allows folds on markers and indentation.
Together, they create a more consistent (and feature-complete) code-folding
system.

Most vim folding keys should work, e.g. =zr=, =zm=, =za=, =zo=, etc.

** Hacks
+ Automatically moves to new window when splitting
+ From visual mode, =*= and =#= will search for the current selection instead of
  the word-at-point.

** Differences from vim
+ Column-wise ranges in ex commands are enabled by default. i.e. the range in
  =:'<,'>s/a/b= will only affects the visual selection, not full lines (see
  ~evil-ex-visual-char-range~).
+ =:g= will incrementally highlight buffer matches.
