>But unlike minimizing or maximizing an app from the Dock, each "stage" can contain multiple app windows from multiple apps; switch from one stage to another, and every window on that stage will pop back up on your screen in exactly the arrangement you were using before.
How does this new feature perform with external monitors? One of my gripes with macOS is how awful it's at managing windows. For example except for Slack, Outlook, Zoom, and a Brave window for listening to music on YouTube that stay in the MB's display, all the other apps go into my external monitor. However every time the computer goes to sleep, I must move a bunch of windows back to the external monitor. I was using Stay [1] and it was doing a decent job, however I couldn't justify paying $15 after the trial ended.
