When I launch an application from the dash I just need to type a few letters and when I see the application I want, I just click on it and it opens.
The problem in the Files & Folder lens. When I see a file in the list, I need to click on it and then it will go down one level and give a few options (Open, Show in Folder and Email) and then I can open it.
Is there an option where I could skip this one level so this file would act as an application?
