I think these buttons weren't too responsive for about three major MacOS versions

The "Liquid Glass" button slowness on macOS is tolerable (coz I can really point at the center of a button with the mouse pointer) compared to the same problem on iOS 26. I have to literally tap several times on core system UI elements like navigation bar left and right buttons for the touches to register, this is Bad.

Agreed, I've blocked all notifications for years. Maybe it got worse recently, but I thought they were annoying since at least Big Sur.

Also went from one click to two clicks

The notification buttons have always felt a little squishy and unresponsive since they were added. They’re terrible.
