Hi, I think you all knows what Ubuntu is :)
You know that Ubuntu added Unity interface in order to improve user experience with Linux.
They are adding new lenses to Unity Dash. What is a lens? A lens is a tool which permits to make specific searches, on your pc and on the web (latest lens is abour cook recipes, for example). Why don't you get in contact with Unity Lens Programmers and you create a lens for make searches through DDG or why don't you create your own? In this way you don't have to open a browser in order to search but you can search directly on your pc. What do you think? :)
