Terminal Transparency Pinguy 14.04 Mini

Hello - Thanks For the Help / Pinguy 14.04 LTS Mini 64

I'm looking for a way to adjust the Termainal Transparency.

I would normally go to (Edit, Profile-Preferences, Background)

And find a Transparency Slider option - Unless I'm missing something It seems that options is not there.

Is the option found in another place now?
