;;; window-manager.el --- Functions augmenting my usage of EXWM. -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>

;;; Commentary:
;; I switched to EXWM from i3, and I haven't looked back.  One day I may write a
;; poem declaring my love for Emacs and EXWM.  For now, I haven't the time.

;; Wish list:
;; - TODO: Support different startup commands and layouts depending on laptop or
;;   desktop.
;; - TODO: Support a Music named-workspace.
