Use one of the following methods to open a new Control Center:
The new Control Center opens in a separate window.
If you open a new Control Center by selecting the Control Center-->New Control Center or View-->Control Center menu choice, the new object tree is identical to the first. If you open a new Control Center by clicking on an object or folder and selecting the Open new Control Center menu choice, the new object tree starts with the object you selected.
With a second Control Center, you can work with two or more objects that are not easily displayed in a single object tree or contents pane. This feature is especially useful when you want to look at the contents of two folders at the same time.
