Edward Lee, one of the primary developers of the Smart Location Bar (aka “Awesome Bar”), has written a blog post outlining some of the upcoming Smart Location Bar changes that will appear in Firefox 3.1. “[T]here’s some new ways to change what shows up in the Smart Location Bar such as restricting results to show only your history (and not your unvisited bookmarks) or matching only in the URL instead of also in the title. Additionally, you can see your Smart Keywords queries show up in the drop down.” For details, see Edward’s full blog post.
