How can I return to the home page when the Ribbon is turned off?Do I need to turn on the Ribbon just to do that?
If you turn the ribbon off, and then go into a drilldown, there is no way of returning to the home page. You have to turn the ribbon back on just to do this. The previous version had an X button at the top right of every drilldown to do this.
You can return to the home page without accessing the ribbon. You can click the back button which is in the title window, and therefore always visible.
