This may be more from an admin standpoint but once I add workers into a cluster (controller token added), I have no way of knowing if the worker is now added to the cluster unless a workflow starts getting serviced and I view it from the 'View schedules' tab.
This causes issues specially when we have to add multiple of them and need to keep a track of which ones are added to the cluster or not.
On the admin page, I should be able to view the list of the workers that is currently existing on the cluster.
