I have downloaded 12.04 and installed it under VirtualBox. The launcher in its default format is unsuitable for my needs.
The two main factors that I need to edit are (1) the size of the panel; and (2) the order in which the launch items are listed.
From the settings I have reviewed, it is not clear how to do this. How do I achieve this?
Its now very simple to change the launcher size in 12.04:
There is a similar excellent answer for moving icons in the launcher:
I use myUnity to do such changes
This worked for me in 12.04 and Unity-2D.

To resize the panel you can use Unsettings.
About the order, well, you can just drag and drop the items in what order you please.
This is actually pretty simple. To resize the Unity Launcher you have to go to the desktop Background options where you will find the slider which you can use to adapt the size.
