This is really cool. Greg from Raizlabs has pointed out that Google Chrome uses the scrollbar to show search results frequency. I haven’t noticed this before and it has really impressed me because it’s a very clever feature. Here’s what it looks like when you do a search on a page:
<img class=”alignnone” title=”Chrome scrollbar during search” src=”/images/0809/chrome_scrollbar.png” alt="” width=”469” height=”427” />
You can see a bunch of yellow stripes in the scrollbar on the right. This shows where the term I searched for appears on the page. Would definitely love to see this implemented in other ways, for example on search engine pages as Greg suggests, as well as in other applications.
