Batboard

I am considering having some options added to one of my radios. What I am interested in is a breakdown of what each option can do. I have the document "flash" from batlabs, but would actually like a more detailed description of what each does. Anyone have anything or willing to help me out with this? Might make a good sticky or a link on batlabs. Also if this is asking too much, I would at least like a description of what features and capabilities the QCII option would add on an MTS2000. Thanks
