My least favorite animation is in Mobile Safari, when you tap the search bar and it expands and brings up the controls at the bottom. There's a sort of shiny sweep transition from top to bottom, but it's distracting and it's not obvious why it exists. I assume it's to highlight the bottom control bar, but that's just a guess.

I also notice that CarPlay has more contrast now, and not much Liquid Glass. Kinda telling.
