Spotlight has replaced app search.
In-app file browsers have replaced a lot of Finder functionality (project views, file views, browsing etc. in IDEs and power tools).
And given how anemic Finder still is, I wonder if its use among power users is very low.
I mean, sure, usages changed (even if not for everyone) but even for someone "just browsing downloads", the new design is not better.
Changing/modernizing the general theme of the OS ? Changing colors ? Textures ? Fonts ? I’m not against it and it’s an age old tradition at this point. But why mess with the general organisation / visual clues / layout to make it less functional especially when your users are already happy with the current design ?
It’s change for the sake of change, not to build a better tool for the user.
