One thing I would love to see is the ability to create groups in IPAM based upon dynamic filters. ipMonitor can display monitors in a 'Smart Group', which is defined by a dynamic set of criteria, as can Orion in the configuration of some of its dependencies. It would be awesome if IPAM could do this in the left-hand pane. For example, you could create a filter for subnets or supernets (or both) based upon a custom property such as 'Router ID' or 'Location'. This would provide the benefit of keeping your supernets in a specific hierarchy while also adding the ability to see all your subnets assigned to a particular location or router (or anything) in a different hierarchy.
Marked for PM to review.
Great request, I've logged this.
