Not sure if it has always been this way, but there is no drop down indicator on the dashboards page. Unless your in GS every day - which most execs and other senior stakeholders are not - there's no visual indication there are more than one dashboard.
I had to double check - because I remember there being an indicator arrow there by default. Now it's not appearing until you hover your mouse over the Dashboard name. Having the indicator arrow again would be awesome - especially since as Tyler said, it's what lets people know there is more than one Dashboard available. [Good find Tyler!]
