This is on purpose. The user manual button from title bar, how many times did we actually used it? We can press F1 to open the user manual. I replaced that button with the Theme switch button which is used more often. Reset default appearance was also removed because with the new layout, I could not find a place for it.
oh alpha setting for accent color got reset with this update, i had some troubles to find why the icon was so visible despite of using opacity 0.1 but it's ok now thanks
