The Window Chrome of Our Discontent

The procession of screenshots showing the Pages toolbar changing over the years is incriminating. For years the UI has been sliding in the direction of being simpler and (arguably) prettier, at the cost of being harder to understand and use. But all of the designs through Big Sur seem to at least be usable, even if they were making compromises to UX for the sake of clean-looking design.

And then you get to Tahoe and both the UX and visual design completely fall apart. The separation between chrome and content is literally blurred, and the visual hierarchy is unclear. (Are the buttons on the right part attached to the top toolbar or the sidebar? There's no way to tell!) It doesn't look clean, it's just a mess.
