Stars darken as a visual indicator of interest
- When viewing results, the stars display how interested you are in a site. If the star is yellow, you have bookmarked it. An outlined star is a site you have visited once, and a dark star is a site you have visited many times.
Multiple search terms
- Separating search terms with spaces allows you to match multiple parts of the URL. For those cases when you are thinking "I know the page was on wiki.mozilla.org, and had schedule in the title..."
- use the default favicon when no favicon
- limit favicon to 16px x 16px (like we do elsewhere)
