The node details block is desperately in need of manual editing. We shouldn't need to edit a cisco config to add location data when simply adding it to the node detail page suffices. Same for any other field in there.
While I'm aware that you can configure SNMP (if available) to pull this information from a device and/or use custom properties to add the location or other fields that's extra work, and extra noise on a node view. Simpler to let us just edit the node properties since user experience should be the primary focus on a monitoring tool.
