It is a good article but only starts to go into features I consider important for an efficient desktop system.
Select/single click paste. This is the big one. it turns copy/paste from a deliberate action to a natural motion. It always surprises me how infuriating going back to hotkey copy/paste is.
Point to focus. Point your mouse at what window you want to be active. Not a huge deal but it goes well with the next point.
Don't raise on click. usually I want a window where I am looking something up. And a window I am working in. I hate it when the window I am working in jumps to the top on focus obscuring the window I am looking at. It should only raise when I click a specific spot(usually the border).
If you get this far you realize that overlapping windows are not doing much for you. so you start using tiling window managers. Unfortunately some applications interact badly with tiling window managers. If you have such an application you may never reach this point of desktop efficiency.
I admit, I was skeptical when I started reading your comment, by the end I was thoroughly convinced. Even with good hotkeys for tiling window management and switching, there's still a lot of friction in my setup.
Envious since I probably can't replicate all of your features on MacOS.
Don't raise on click: if you can remember to cmd-click, this mostly works, even with right-clicking. The window receives the click and doesn't raise.
Point to focus: you can get this with yabai [0]; note that it recommends disabling SIP (and keeping it disabled) so that it can install some hooks into Dock.app, but you don't need to do that if you only want focus-follows-mouse.
select/single-click paste: you can get pretty far with hammerspoon (hs.eventtap to notice mouse drags, double-, and triple-clicks, and then use hs.uielement to get the text that is selected), but it's handicapped by apps that don't play nicely with accessibility (browsers and electron apps in particular come to mind). [1] has an alternate way which notices selections as above and then uses hs.eventtap to send synthetic cmd-c keydown/keyup events, but I haven't tried it.
edit: now that I think about it, I think you might be able to do the don't-raise-on-click behavior with hammerspoon as well, by capturing click events, checking their `mouseEventWindowUnderMousePointer` property (see [2]), and if that is not the window that is currently focused, block that event and send a synthetic copy with cmd- added (and if cmd- is already in the mod mask, treat it as "I want to raise that window" and do the opposite -- block the event, copy it and remove the cmd- modifier, and post that synthetic event)
