Virtual desktops (accessible with keyboard shortcuts) are a must IMO. I usually set up ten of them at a time- MacOS is actually mostly ok in that regard, expect for the fade animation you can never turn off, and the fact that as soon as you full-screen a window, the system insists on moving it to a totally new workspace (that can’t work with any your predefined shortcuts), instead of just full-screening it within the current desktop. What were they thinking?
