Change Unity launcher size

As mentioned in the previous post, you can tweak some of the unity settings through compizconfig-settings-manager. Install and run this application.
Next, click on Ubuntu Unity Plugin, and you can use a slider to adjust the size of your launcher.
This is particularly useful for those of us using Unity on a netbook.
You may want to take some time to play with some other settings while in the application as some of them are useful.
