 ** Olivetti
 Olivetti provides a focus mode for Emacs, which makes it look a bit
-nicer with fringes.  I also define ~+olivetti-mode~ which will
-remember and clear up any window configurations on the frame, then
-when turned off will reinsert them - provides a nice way to quickly
-focus on a buffer.
+nicer.  It uses margins by default and centres using fill-column.  I
+actually really like olivetti mode particularly with my [[*Mode
+line][centred mode-line]], so I also define a global minor mode which
+enables it in all but the minibuffer.
