Hi will,
The script library allows you to script all of the parameters found in the Scene Manager via VBA macros, as shown here:

There is also a detailed explanation of the library and its use in the plugin's help files - I think you'll have to download the help .zip for now, but it will be available on-line as well shortly.
Just let me know if you have any questions about it.
Cheers,
JD
