The reunion mod dropped support for menu overhaul a while ago. The version in 7th heaven is R03 (comes with newer font and the Menu Overhaul). From then on there is no MO.
Also 7th heaven dev Iro is no longer around, so the app itself is kinda stalled.
I guess most people around are old school and like the old menus.
Try asking in the 7th heaven subforum, in the mod request topic.
