I ranted about this in another thread, but Liquid Glass is the final nail in the coffin for me. I've been disappointed with Apple's UI evolution for years now, especially in macOS. Main things I dislike about it:
- It looks tacky and dated, whereas iOS 7-18 looked clean and classy for the most part.
- The liquid animations, whilst cool at first, started becoming distracting and annoying within days.
- Legibility of key UI elements is massively worsened versus the previous design language.
- The main Liquid Glass elements look more like colourless jelly or goo than actual glass. They actually look quite gross, especially if you have a photo or complicated image as your wallpaper (or the UI is floating over images etc).
- The glass concept is very inconsistently applied across the UI. The Settings app, for example, is barely any different.
- Space is less efficiently used to make room for shadows and extra padding (especially in iPadOS and macOS).
- I especially hate the continued obsession with hiding controls in menus and pop-ups! As displays have been getting bigger, fewer controls are being displayed!
- Replacing the bottom tab bar with floating blobs is actually more distracting, as your eyes are drawn to how they're sat on top of the content. An opaque bar at the bottom was cleaner as it felt part of the edge of the display. A great example of this is in Safari, especially with how the UI shrinks to a small pill-shaped blob. That blob feels more like there's something stuck to the screen than an elegant UI that 'gives way to the content'.
