Yes, the old grid layout was not good for anything that you didn’t access frequently. It was sometimes hard to find things if you didn’t already know where to look.
I agree that the actual settings controls and panel layouts are not as good as before. They are more autogenerated while the old panel layouts were more carefully planned. some of the controls seem poorly suited to the data they are controlling.
It might have been better if the navigation were changed but the original controls retained.
