This is an awesome project. I have 2 questions: * Did every OS treat clicking in the blank space above and below the scroll bar the same, like this website seems to suggest? And, * Why'd early versions of Apple's OS have the buttons on the bottom? What was the rationale & why'd they give in and move them to the top? I kind of like the bottom buttons. |

On very old Unix desktops (classic Athena widgets), left-clicking anywhere on the scrollbar meant "scroll down" - if you clicked near the top, it would scroll down a little, if you clicked near the bottom it would scroll down a lot, and if you held down the mouse button it would keep scrolling at that speed. Right-clicking meant "scroll up". You had to middle-click to actually move the visible bar to a particular point.
The point of putting the scroll buttons together was to make small adjustments easier. Scroll buttons are fairly small targets, and the other end of the scroll bar can be a long way away, so if the other scroll button is at the other end, it can take a while to travel precisely to it since humans can make small, accurate movements and large, inaccurate movements but not large, accurate movements. On the other hand, if the other button is right next door, you can get there quite easily.
