Is there any way to disable this behaviour altogether? After almost a year of being forced to use MacOS at work, I still can't wrap my head around having two sets of window to switch between (inter-app level + intra-app level). I REALLY wish they included an option to just treat all the windows as top level!

Edit: found elsewhere on the thread this app that purports to fix it: https://alt-tab-macos.netlify.app/

There’s never gonna be a first party way to change this because macOS has always been “app-centric” whereas Windows has always been “window-centric”.

It’s two different takes on the desktop metaphor—same reason that apps (usually) remain running on macOS even once you’ve closed the last window, which is another difference that often annoys both sides when they have to use the other OS.
