The At A Glance is available as part of the Matter Planner interface.  The At A Glance section is to allow you to see the 'vital statistics' of where you are with the matter.  The Matter Planner: At A Glance is for viewing activities and milestones in a visual fashion.  You can see if you've got  milestones setup (to break larger matter into smaller manageable chunks), budgetary information, and Invoicing issues.
