There's no feedback while searching in the application launcher, so you don't know if it's still searching or nothing has been found. Reproducible: Always Steps to Reproduce: 1. Click the K menu to open it. 2. Type something that shouldn't be found. "akajsldkfjal", for example. Actual Results: Nothing is shown. Expected Results: "Searching..." or some kind of animation is shown indicating that the search is in progress. "Nothing found", when the search has finished and nothing has been found.
