Show me the code! – By Davanum Srinivas

Many many thanks to fern on #ubiquity. With this version, you can view all the URL’s as you type them and view the preview at the same time as well. Basically fern’s code generates a list of URL’s which are available as nouns to Ubiquity and Ubiquity displays them as suggestions. Take a Look how simple the command itself is now as compared to the previous version/

Here’s the screenshot:

Here’s the code:
