Currently spaces are listed in a flat list. It would be useful if they could be grouped together in one (or more) ways. Take the following spaces for example:

Bob's Personal Area
Dan's Personal Area
Product A Documentation
Product A Development
Product A Support
Product B Documentation
Product B Development
Product B Support

Although they are spaces in their own right, it would be nice to have the following grouping possibilities (containing):

Personal Area's (Bob && Dan)
Product A (Doc && Dev && Support)
Product B (Doc && Dev && Support)
Documentation (Product A && Product B)
Development (Product A && Product B)
Support (Product A && Product B)

So a space could be in more than one group, and groups could be hierarchically nested. A group view of the dashboard would be where you see them.

Just a thought ...
