It would be nice to have the ability to create a node from an unbound agent tunnel.
If the Agent configuration includes a Zone ID, it should be possible to search if such a node already exists in the system, e.g. by checking IPs & hostname? That could also be used to automatically bind tunnels to existing nodes if there is a 100% match.

Even just having the ability to right-click on a node in the Agent Tunnel Manager and selecting "Create Node" would be helpful when you roll out Agents to dozens/hundreds of nodes.

Cheers
