very happy to read your post.With Liquid Glass Apple made it clear that they wanted these onscreen elements to look like glass, we are leaning into the "computer thing looks like real thing" skeuomorphism-ish territory again. When we moved away from skeuomorphism with iOS 7 (and sorta Mavericks but really Yosemite) the design of applications and the OS looked like something that could only exist on a computer. I personally think, despite some misses, the design and behaviour of macOS and iOS peaked with macOS 10.12-10.14 (Sierra - Mojave) and iOS 10-13.
I can only speak for iOS and iPadOS as I have not updated to Tahoe on either of my Macs. Some parts of Liquid Glass look really good. I think the quick toggles look great. I like the volume and brightness sliders. I love the effect of pulling down the Notification Center. The problem with Liquid Glass is it is not consistent. The toggles are a refreshing take on what we had before while showing off the improved graphical capabilities of the hardware it runs on, but the X and checkmark symbols replacing "Cancel" and "Confirm" look amateur. In both cases the end result is the same but the aesthetics have changed. The windowed multitasking on the iPad is neat but in the process Apple butchered the already, in my opinion, functional multitasking present in iPadOS 18. The floating panels often waste space, especially in apps where information density is important like Mail and Files, and it is clear that Apple understands this because of how Mail and Finder behave on iPadOS. In landscape the apps have the floating sidebar but when rotating into portrait in Mail it reverts back to the old layout with the two distinct sections and in Files the sidebar is hidden and needs to be summoned, which introduces its own frustrations. None of this is even mentioning the lack of consistent search bar/icon placement in Apple's own apps.
I think Liquid Glass can look good, it has potential, and I like the idea of the UI looking like the material I interact with it on. However, I think Apple should rethink some of the ways in which they are using the glass aesthetic. They should tone down that wasted space to allow for more room for text and content to sit comfortably. I also think that while the floating buttons and options look neat for a tech demo there have been plenty of screenshots where it looks messy. The content of the app and the UI of the app should be more separate, I think a blur of about 20% would help with readability and the appearance of onscreen clutter a lot in those cases.
i am looking forward to iOS27, with improvements to the overall implementation of Liquid Glass's design elements.
you mentioned about pulling down the notification center: i too am a huge fan of the way it works on that screen.
i find myself pulling the screen down slowly, slowly, seeing the way light and depth and flow of color are handled. just beautiful.
how do i want Liquid Glass improved ? i want apple to work on improving its algorithm so that the rest of the system can match this page's effects.
and agree with your comment about separating UI elements from contents elements.
and, hope that apple provides some ways to lessen all of its affects for users who can't appreciate it's beauty.
