Using Keynote.app for the first time since macOS Big Sur. Boy, the shift to smaller all monochrome icons is a big usability loss.
Guess what, these cones in your eye are great things, you should use them.
I think about this every time I have opened the iWork apps in Big Sur. The icons in the toolbars are smaller, they are monochromatic, the button click target is barely bigger than the icon, and the click target only shows on hover after a delay. It is like this in every iWork app.
The change from the glossy and dimensional era of the Keynote toolbar to the post-Yosemite flatter appearance was a question of taste. This transformation is a usability regression.
