Dialog Skins - New Style Ghost
Applying this option will choose this skin for the display of new style dialogs as shown below:

Note: The main background of this skin is actually a modified version of the skin used in the Ghost UI. The Ghost UI has some windows are nearly transparent by default. When you hover over these windows with your mouse the background of them darkens to something that is less transparent. I did not duplicate that action in this UI. You can however right click in any of the windows and adjust the alpha level of them to make them more transparent to get an effect similar to what is used in the Ghost UI.
