The "Lion" version of the Macintosh operating system removed what was, to me, a very important feature -- the arrows at either end of scrollbars. I found this out when I bought a new laptop, which I'm using now to write this piece, and discovered the omission. I wrote a blog post about it at the time, and was told by Mac advocates not to worry that I would discover better ways to do the same thing. That didn't happen, but since I don't use the laptop that often, I muddled along without the arrows.
