How to get Unity dash overlays maximized by default?

The dash is designed to open "half-way" for screens that are larger than a standard netbook. This is called "Desktop" mode.

You can force it to use "netbook" mode through the following:

gsettings set com.canonical.Unity form-factor 'Netbook'

If you want to reverse this try

gsettings set com.canonical.Unity form-factor 'Automatic'

or

gsettings set com.canonical.Unity form-factor 'Desktop'

Alternatively, you can install the configuration editor dconf-editor from the package dconf-tools and do the same the graphical way:

There is also a rather neat overlooked method...
