There are more than four options, in fact, it's practicly unlimited. "Only Global preferences, home, work and school (in lower case!) are supported by the projects." just means that the projects themselves don't show prefs with a different name, but if you create a pref named 'StarbuckPref2' this will be send to your hosts, and you can set the host to use this pref.
Please do not PM, IM or email me for support (they will go unread/ignored). Use the forum for support.
