Enabling advanced features in Fortigate firmware 5.0

You can enable some hidden/advanced features in Fortigate OS 5.0 via System -> Config -> Features and turn on Advanced Routing,

In my case, I was looking for "dead gateway detection" so I could switch to my secondary ISP when my primary ISP failed, but the option wasn't there in Router -> Static -> Settings.  Once Advanced Routing was turned on, I had the option for dead gateway detection.
