I'm not sure if it's pure nostalgia but I long back to the "Lion era" of OS X.

Apple had a HIG and third party developers used it. Different apps looked consistent: toolbar, sidebar etc.

Apps had borders. If there was too much content there were big blue scrollbars.

Buttons had borders. Windows had texture. You could find stuff.

I could go on forever. But the OS was simultaneously better visible to the eye, and less visible to the mind. Stuff worked.
