Omnibar is exactly what I was looking for since Apple introduced extensions to Safari. Thank you for providing it!
The only thing I miss is a possibility to configure the shortcuts and the search engines and not only the default search engine. So f.e. I'd like to add a shortcut for the german wikipedia. I had just a quick look on your code. But I think, if it would be possible to configure the array ENGINES (in omnibar.js) it would be really great!
Kind Regards,
Pascal
