I just had an atlas workshop. The trainer changed a cluster and got the "We are deploying your changes ..." blue bar at the top.

But he also got a "AUTOMATION STATUS" button in there, showing a very helpful table reflecting the changing cluster members and tasks in real time.

I asked in the chat and got the info: "Unfortunately, this automation status button is only available to MongoDB employee accounts."

I'd like to see this feature released into the wild.
