Global Dashboard Configuration Is there any way to change the default configuration for the Dashboard globally, or per user group?

I don't mind Sysadmins seeing the Blog &amp; Tonic feed, but I don't want Members (who access the CP only to add calendar events) to see Blog &amp; Tonic. It will just cause confusion for those users.
Have a look at One Dashboard which works nicely. I've used it to set each users Dashboard to show a collection of pre-defined Analytics widgets.
