macOS Monterey Automatically Resizes Windows Moved to a Secondary Display

Apple announced macOS Monterey this week, and one small but convenient feature that went unmentioned during the WWDC keynote is automatic window resizing.

Auto Resize in Monterey Feature 2
As explained on the macOS Monterey features page, windows now automatically resize when they are moved from a Mac's built-in display to a secondary display, including an external monitor, another Mac, or an iPad using Sidecar.

This feature should prove to be particularly useful when moving windows between a smaller MacBook display and a larger external monitor.

Another new window management feature in macOS Monterey is the option to display the menu bar at all times when an app is in full-screen mode, making it easy to view an app's various menus and other glanceable information at any time.

macOS Monterey is available now in beta for developers, with a public release likely to occur at some point between September and November.

Menu bar on in full screen is going to be great. It is annoying having to slide back to a normal desktop to see the time or push the cursor up to the top.

Will we be allowed to pin the dock to one monitor instead of having it jump around when we hover the pointer at the bottom of the screen?

Wow so Apple can improve the UI with external displays on macOS? Incredible! They should talk with the iPadOS team about that!

I just want applications to open on the same monitor I select them. I don't understand why that's too much to ask. If I have three monitors, and I click the icon to open an app on the far right monitor, I don't want it opening on the far left monitor. And I'm not talking about applications that were already open. I understand why they wouldn't move from monitor to monitor.

Maybe this time they'll fix Safari's white space below the loading bar when its full screen on different displays? Hopefully they will in Monterey now that they are changing it's UI. Minor glitches like these remain unsolved for years.
