Tabbed Emacs

You like Firefox’s tabs to clean up your screen and keep an overview of which pages are open? Of course Emacs can do that as well: elscreen.
With the following code you can open new tabs with C-t and close them with C-x C-c (yes, the way you normally quit your Emacs; Firefox uses C-w which is used in Emacs for cutting text though). Every tab can be split into windows as you like of course.
;; Elscreen - http://www.emacswiki.org/cgi-bin/wiki/EmacsLispScreen
(load "elscreen" "ElScreen" t)
(global-set-key (kbd "<C-tab>") ‘elscreen-toggle)
(global-set-key [(control shift right)] ‘elscreen-next)
(global-set-key [(control shift left)] ‘elscreen-previous)
(global-set-key [(control t)] ‘elscreen-create)
(elscreen-set-prefix-key "\C-j")

;;; C-x C-c closes frame or tab
(global-set-key "\C-x\C-c" ‘intelligent-kill)
(defun intelligent-kill ()
"quit the same way no matter what kind of window you are on"
(interactive)
; (kill-buffer (buffer-name))
(if (and (not (elscreen-one-screen-p)) (elscreen-kill))
(message "Killed screen")
(if (eq (car (visible-frame-list)) (selected-frame))
;;for parent/master frame…
(if (> (length (visible-frame-list)) 1)
;;a parent with children present
(delete-frame (selected-frame))
;;a parent with no children present
(save-buffers-kill-emacs))
;;a child frame
(delete-frame (selected-frame)))))
