I recently taught my users to create their own dashboards, and some of them started sharing them. Now I am seeing new dashboards pop up in the list, and I am worried it will grow too large.

I was thinking it would help if you sorted the dashboards into groups:
- my dashboards
- global (shared by admin user) dashboards
- other shared dashboards

This way, the important ones can show up first, rather than embedded in a long list.

There would need to be a way to identify a dashboard as 'global', so that users other than "admin" could create them.
