Bevy is an application launcher that shows all of your applications in a single window that can be opened with a global hot key, from the menu bar, by mousing over a corner or edge of the screen, or by clicking its dock icon.
Bevy automatically searches a list of standard application locations and creates a visual group for each folder in the list. In addition, you can modify the list and add your own unique application locations. To help you quickly find the application you're looking for, a key press will highlight applications with matching names or you can drag-and-drop a file to highlight compatible applications. How cool is that? In addition, you can hide rarely used apps and un-installers so they won't clutter your window. And Bevy is always up-to-date because it uses Spotlight to keep track of changes so you don't have to.
