+** Show a “beacon” when cursor position changes
+
+   #+BEGIN_SRC emacs-lisp :tangle no
+     (depends-on "beacon")
+   #+END_SRC
+
+   =beacon-mode= is a new minor mode that shows a temporary gradient
+   whenever the cursor screen position changes in a (somewhat)
+   unpredictable way. For example, when you switch buffers, when the
+   window scrolls because you’ve reached the top of the window, etc.
+
+   #+BEGIN_SRC emacs-lisp
+     (beacon-mode)
+   #+END_SRC
+
+*** Don’t show a beacon everywhere
+
+    Beacon by default already doesn’t show in certain buffers with
+    certain major modes, currently only =magit-status-mode= disables the
+    beacon. I have some more that I’d like to add.
+
+    #+BEGIN_SRC emacs-lisp
+      (stante-after beacon
+        (setq beacon-dont-blink-major-modes
+              (append beacon-dont-blink-major-modes
+                      '(circe-channel-mode
+                        circe-server-mode
+                        magit-diff-mode
+                        gnus-summary-mode
+                        gnus-group-mode))))
+    #+END_SRC
+
+*** Show a beacon when recentering
+
+    Somehow I always get confused when I recenter my screen, is it in
+    the center, top or bottom? Beacon disables itself for the
+    recentering command, and I want it enabled, even though this is
+    completely predictable.
+
+    #+BEGIN_SRC emacs-lisp
+      (stante-after beacon
+        (setq beacon-dont-blink-commands
+              (delq 'recenter-top-bottom beacon-dont-blink-commands)))
+    #+END_SRC
+
+** Show some extra highlighted lisp symbols
+
+   There exists [[https://github.com/Fanael/highlight-defined][highlight-defined]], but this is a bit over-the-top for
+   me. I do like the way =js2-mode= highlights defined and undefined
+   variables. Hopefully this package comes a bit closer to how that
+   works.
+
+   #+BEGIN_SRC emacs-lisp
+     (add-hook 'emacs-lisp-mode-hook 'lisp-extra-font-lock-mode)

 * Final touches
 
   These options and calls need to come last so they don't interfere
