There is one feature I have been wanting for a long time, Dashboard Sharing. I manage quite a few websites and really disliked the idea of having to create the same 4 dashboards for 30 different sites.
4 Dashboard X 30 Sites X 12 Widgets / Site = 1440 Widgets to create.
Not a fun way to spend a day.
Well now this is no longer a concern. Google has implemented Dashboard Sharing.
