Besides common stuff, Voice provides some cool page features and customization which are described below. Go Theme Options -> Page Templates to manage global settings for page sidebar and layout.
Find out more about sidebars in the Sidebars sections of this documentation.
After you are finished with global page options, you can go to Pages -> Add New.
You can then set a specific sidebar for each page. You can inherit from global page settings (as default) or specify layout and sidebars for a particular page only.
