Ubuntu has a new feature for the unity desktop, you can “search” for commands in menus of (seemingly) legacy apps and across programs. It creates a really cool console way of interacting with GUI programs. This is better than windows’ search the start menu for programs which I also like a lot. Damn, the HUD looks like it could be better than tab completion, or browser address boxes that Google search! Apparently its planned to take voice commands too… woo!
