I upgraded yesterday. Stage Manager mostly stays out of your way even when it's enabled. Its addition means macOS now has 3 modes of interacting with windows: - The Classic way, with piles of overlapping windows in a single desktop, and the ability to minimize and hide them. - The Spaces way, allowing for full screen apps and also multiple desktops containing separate sets of windows. - The Stages way, which allows to arrange groups of windows from a desktop into different sets, defaulting to one stage per application, but allowing for arbitrary groupings. The key aspect is these three modes complement each other. Stage Manager really makes the system more efficient, productive, and even nicer-looking. It's 100% an old-timer Apple feature. I got a feeling this person would hate Spotlight or Quick Look if those features were to be released nowadays instead of 15 years ago.
