Tweaks based off of user feedback

Much of this week went into implementing various user interface refinements to address issues that surfaced in our user testing. The biggest change is that we're experimenting with a new page layout on the search results page. We've tried to tighten up the filter panel and we changed an ad format so that the actual search results will be visible higher on the page. The page now also makes better use of the browser width. If the browser window expands, content expands with it. We also tried to visually differentiate the tabs so that users will have an easier time recognizing that additional content can be accessed (an issue that arose during user testing). There have been a number of other changes as well.

Over the next two weeks, we hope to conduct additional user testing to make sure that things didn't get worse and to get a better sense of what other problems might exist. If you'd like to participate, please let us know.
