Clicking on anything does nothing. Instead, one has to type, and the UI gives no feedback about that. Because normally you cannot simply start typing in a UI as presented. Then, once you typed the application, you have to press <enter> to launch it. Hmm, ok. I do like the concept, but usability wise this needs improvements, even on desktop. When I press (or touch) launch it should launch the application. May be a bug though.
