> There is a navigation tree on the left of the Overview and Entities pages. 
> Management calls are periodically made to update the data for each node in the tree that is expanded .
> The amount of data requested becomes problematic when there is a large number of router in the network:
> - It takes a long time to retrieve
> - It takes a lot of memory to store
> - It uses bandwidth
> For large networks, the expand all/collapse all arrows at the top of the tree should be hidden and expanding a tree node should automatically collapse the other nodes.
