;;; keybindings.el --- My Evil preferences -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>

;;; Commentary:
;; This module hosts my Evil preferences
;;
;; Wish List:
;; - drop support for `evil-leader' library in favor of `general.el'
;; - restore support for concise (n <kbd> <function>) instead of `general-mmap'
;; - restore support for `general-unbind'

;;; Code:

  (setq evil-want-integration nil)
  (general-evil-setup)
