I've shared some work I did recently in enhancing the Create Table of Contents AppleScripts to include various styles - such as hierarchy style, section titles only and different visual style options.
The files are available to download as well as explanation on how to use & some samples from this blogpost:

Hope they are useful to others. If you use and add an further updates maybe post back here if you get the chance.
