Please switch the default view of the Preferences tool to "Customize Tabs" instead of "Notifications"
Also change the order on the links at the top of the window so that they are alphabetized. (Customize Tabs, Language, Notifications, Time Zone)
This should make the Customize Tabs settings easier to find for users in the short term. Hopefully, there will be a better solution for the long term for the entire Preferences toolset in the next Sakai release (post 2.2)
