"I've been waiting for such a launcher/home screen for a very long time. Been tempted on writing my own  but now I don't need to. A must have for any command-line guru out there. Since you can make aliases  it can cater to Windows command-line users as well. Makes launching apps and making phone calls from your contacts a breeze."
