Org-mode has a nice option which allows you to show
week-end days in a different color in your agenda. That means that Saturday
and Sunday (when I do not work) are fontified with org-agenda-date-weekend.
Since I have started to use Org-mode, I though it was missing something to
have appointment locations on a map. Of course, it's easy to get a LOCATION
property from an entry, and then browse-url on Google Maps.
