I suppose this makes sense if you have relatively few windows that each themselves encompass self-contained task state: one terminal window with a bunch of tabs, one VS Code window with a bunch of tabs, and so on.

I've always found this rather, uh, un-simple to deal with because I both suffer from attention problems and because I tend to want to consider a whole box of windows together as a complete task. macOS's per-appbundle model, inherited from NeXTstep, isn't perfect, but it does at least get closer to what I want.

I used to write software in Delphi, and Alt-Tabbing through several forms and code windows and panels and hypertext documents and compiler error listings and whatnot was just a gigantic pain. It really, really soured me on Windows' way of doing things: I could just never get the mental model down for how windows would stack in the Alt-Tab order given my need to flip between six or seven of them somewhat randomly in the course of working on something.
