I am finding that I want an easy way to switch between dashboards.
I'm looking at Sales and then I want to switch the Marketing.
How about...
Put a drop-down selector [ v ] next to the Dashboard Title (h1) in the upper left corner of the screen and have it show a list of dashboards (w/ stared dashboards at the top of the list, naturally).
A paginated back/next heading at the top of the page.
[<<] Current Dashboard Title [>>]
