Ubuntu HUD in Mac OS Is there and app or something that gives Yosemite the functionality that Ubuntu HUD has - search menu for items?

I am switching to Mac from Ubuntu. Even thou I was on Ubuntu Linux for only a few weeks and originally came from a Windows background, I got super used to the HUD  functionality. I would like to take that with me if possible.
Spotlight on OS X is the closest built-in feature, Use Spotlight in OS X Mavericks to find files and more.

There are third party alternatives that have additional functionality. Well known examples include:


Alfred
LaunchBar
Quicksilver
