The program seems to be no longer updated. Last version, 0.95.3, released on November 2014, can be still downloaded from Launchpad.
I use this everyday, at first I was not sure how good, it was, but once I started using it, I could not stop. It saves having to try and find a program in a long list. As long as you know what the program is called you just type it in, and hist enter and your done. Its amazing.
