1- Include a way to be able to specify a different map for each different node or interface. Currently, if you choose a map to be displayed in the node details view, it will be displayed for all nodes.
2- Include an easier way to restrict a customer's view to a single interface. The most secure way mentioned in the manual "re-add the node in System Manager and manage only the target interface" would impose a limitation on the number of interfaces to be monitored (depends on license) and is inconvenient to manage.
3- Include a way to view events by interface.
