Yes, it should definitely be in the Preferences dialog! I'm not quite sure if it's sarcasm or not. Honestly my first thought when I saw the buttons like this was "WTF is this?!". However, this should not be an application preference! One thing that Apple does (that every company should do) is making choices for the users. Sometimes they're wrong (this one looks dubious to me) but adding settings is the wrong approach to it. I recently started to use a Windows PC (granted it's XP) again and the number of preferences (e.g. system, Outlook) available is completely insane.
