Ubuntu 12.04 Unity Launcher How To

Every time I have to come back to Ubuntu Desktop there is some major change I need to adapt to. I will make no comparisons with other Desktop OS but instead will keep here some notes I found useful for Ubuntu 12.04.

1. You run applications by searching for them via "Dash Board", the top icon from the Launcher (the by-default left bar)
2. You can add a shortcut in the Launcher to a particular application: Run the app, right click on its icon from the Launcher and select "Lock to Launcher"
3. The bar can autohide if you use the "Appearance" app, "Behavior" option
4. The Launcher is buggy at least in 12.04 so it might disappear, freeze, God knows what else. You just need to be able to connect to the console and run the below (which will restart the box and try to rebuild all compiz related settings)

   $ mv ~/.config/compiz-1 ~/.config/compiz-1.BACKUP
   $ shutdown -r now
