I sure would not start to learn Sony xml with this mod, but good luck anyway
There is only one other person on this forum that I know of that could possibly help you get this updated (before I get the time to) as he is / was quite familiar with the UI a long time back now ... I will not say who.. but I know he will read this and if time allows maybe he will help..
Sorry I can't do more .. I feel bad enough about leaving UI's unattended
