The same happens on the navigation bar.

This happens only when drag and dropping the toggle button. If you just click there’s no glass animation.

It’s a super nice animation that no one will ever see, but brings consistency and adds a nice touch to the UI.

On iPhone you can trigger this gorgeous effect by dragging the selector when navigating between pages instead of clicking on the pages (but who would do that?)

The best way to appreciate Liquid Glass is by using an iPad with a mouse. The interactions are incredibly satisfying.

Obviously these hover effects don't work on iPhone (unless you drag and drop the selector) and on macOS they are toned down a lot.

Interested to see how consistent this will be.
