I would like to customize the top-right default search bar in Safari (Google, Yahoo!, Bing) to search specific websites such as dictionary.com, youtube, etc. I previously used Glims to do this, but Glims no longer works with the new version of Safari. That being said, I found that Glims was buggy even when it did work, so now I'm looking for a permanent alternative. Essentially, I love the quick search feature, but I want it to search specific websites of my choosing. If possible, I would also like to remove the Yahoo! and Bing search engines (but keep Google). Any help would be greatly appreciated!
