AddOutputPane function (automation interface)
Syntax: AddOutputPane " <pane name>”
Where <pane name> is the name of the pane you want to create.
This function creates a pane.
The pane is similar to the Output pane and you can write to it through the DisplayOutputPaneMessage function. You can remove the pane through the RemoveOutputPane function.
* 
If you close the pane in Modeler by right-clicking the pane and clicking Destroy Pane, the pane is removed from Modeler and not just hidden, as is the case with other panes.
For example, this script creates a pane named My New Tab.
Studio.AddOutputPane "My New Pane"
