Not sure if this is what you meant, but Ubuntu mimics this in Unity... in fact I think most Linux DEs now come with something similar...

Like someone else said, that's like the Mac System menu. The difference is subtle, but very important: Each group is self-contained, so the icons reflow only within that section if the window is resized (if the window even allows resizing).

That's much more like a copy of the Mac's System Preferences, really.

But crucially the mac pane can't be resized or reorganized.

In practice, I use search for the configuration option every single time on mac. It's great.
