Customer service management system properties

[marclindsay]

I am looking for any information on the following System Properties related to Customer Service Management application and Special Handling Notes. Want to understand exactly what these system properties turn on? 

Version Xanadu and/or Yokohama

Thank you

Still does not answer my question. After installing these plugins, these system properties do not exist, but I am still able to see the links and manage notes with accounts, contacts, etc.. 

I still don't understand what these system properties are actually doing? or controlling?
