I like the new OmniBar in Safari but I don't like the limited options for search. Matt Swain's plugin gives me back my DuckDuckGo search with Safari 6. Previously I used LaunchBar for all of my web searching.
The plugin also makes the search results URL appear in the address bar. Nice addition to Safari. That's something that required hacks until now. How is this free?
