I really like the demo/tutorial style:
- it shows quickly and easily what the library can do
- it shows it from really simple example to more complicated one
- it gives enough details to understand what the option and the code are doing while not over explaining it since if the user wants to know more he could go look the documentation.
In the vertical scroll bar, if you drag a little up and down and at the same time move the pointer right outside the browser window onto the desktop, you can still scroll. The
behavior seems strange to me, but perhaps it is typical. (The browser is Safari 5.0 on MacBook with OSX 10.5.8)
