> It's as if Windows 7 just continued to slowly iterate and add useful polish.

That's a pretty good description of it, I even have KDE laid out the same way I did on Windows 7 (or more accurately I guess on KDE going back even further since Linux has been my main OS since the 90's with Windows relegated to gaming).

To this day - Taskbar shows window titles, only shows window titles for windows on that screen, there is no grouping, there is no ordering except order opened etc.

I think autonomously in terms of which physical screen a window is on and when it was opened relative to others so I know exactly where to look/it'll be - the Mac style (and Linux/Windows style at least out the box) defaults of hiding all windows for an application behind it's icon in the dock never made sense to me, I have widescreens why do I want a doc that only takes up 40-50% of the horizontal space?.
