https://issues.apache.org/bloodhound/ticket/94 is a ticket about making 
Activity areas filter to show events that are specific for the level so 
that drilling down the information is limited to the scope of the object 
being viewed.

At this point we have the dashboard, products and components filtering 
in this way.

Cheers,
     Gary
