> the much-celebrated Liquid Glass opacity slider

The Liquid Glass slider is an embarrassing outright admission of failure. Apple built its brand as a tastemaker, so to put out this new, controversial design language, and after a year of tweaking, finally throw their hands up and say "we don't know what looks good, you decide" is so disappointing.

That said, all the changes in iOS 27 are such a massive improvement from 26. The first design turnout with Alan Dye gone is making me feel very optimistic of their direction.
