That's solved by keeping it in its own window.

That works on Windows where alt+tab cycles between ... er, windows, but not on macOS, where CMD+tab cycles between apps. As another commenter said, the 'shortcut' feature (e.g. for PWAs) is a workaround.

This constantly pissed me off, especially since MacOS always seemed to pick the wrong window to jump to.

There's an open source project to fix it though: https://alt-tab-macos.netlify.app/

Together with an app to fix the scroll wheel and a calendar widget, working with MacOS becomes almost bearable.

CMD-` has always cycled through open documents, going back to the original Mac OS.

Sure, but alternating between the two is less convenient. You can also cycle between tabs using a keyboard shortcut.

You can also type "%outlook" in the address bar in Firefox and jump directly to the tabs that contain "outlook" in their names.
