When I am trying to use your components, I have to look things up on your web site.  Considering you develop web site components, I would think that your site would behave very well.  What I find is that I am often frustrated by web site.  Here is an example:

On this page you basically have three main sections:
The "Api reference" list on the left with a vertical scroll bar.
The "IN THIS ARTICLE" list on the right.  No scrollbar
The actual api methods in the middle which scrolls with the main scroll bar.

But the "IN THIS ARTICLE" list section on the right never scrolls.  I would like to be able to scroll through the list to see possible methods, but I can't.  I know they are there to help navigate to a method but since a bunch of methods are basically cut off .....

Remember that first impressions aren't the only impression.  You can make the sale with your demos, but can you keep the customer with your documentation?
