I found out today that my new Logos 4 "Leaders Version" does not include "showing the differences" feature. I would gladly give up a huge portion of the books that came with this package in exchange for that one feature. I was really disappointed after seeing a demo of this feature, then buying the software and having it not be there. I think that this should be part of the base package or at least available as an add-in. Is there any plans to offer it as a separate component?
