Dashboard Redesign

Once we've finished cleaning up the existing feature-set it seems likely we'll be redesigning the dashboard/homepage. We've talked about presenting information at a per-group level, and providing more of an activity feed, so this redesign could subsume the groups page and most of the notifications and wind up looking more like the daily summary email. I.e. this is a pretty comprehensive overhaul as opposed to an iterative development.

There's been a couple of discussions related to this redesign but I wanted to bring it all under one roof and invite any mockups so we can start thinking about this holistically.
