The scrollbar thing is a more widespread mess. I've seen plenty of apps (cross platform) which hide the scrollbar as a tiny grey bar only visible when scrolling. Which on some TN panels is neigh invisible... If I can't see the scrollbar there is no additional stuff to read. I'm now pretty sure this is apple's bad design leaking though to the rest of the world.
Apple scrollbars have never looked uglier. I would prefer them to always show but they're so ugly I keep it default. On Aqua they looked great! On Windows they're still great!
