To get back a more vanilla Emacs experience, remove :feature evil from init.el. Evil-specific configuration and keybindings (defined with map!) will be ignored without evil present (and removed when byte-compiling).

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 from one place (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
If in 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.
