Try dashboard buttun - what is it?

what is this button for?

Reload returns me to main page.


Preview next-gen UI: The next generation Rancher UI is available in preview mode at the cluster view level. The new Rancher UI provides navigation based on native Kubernetes namespaces. Rancher projects are still available to the end-user for managing attributes across multiple namespaces.
