I looked through to see if you'd already done this but I couldn't see where you had. It'd rock if you have or could hook this one up.
All Black theme menus and everything not just home. If it isn't doable it's no big but it'd rock IMO. I used UITweak and got close but it is kind of clumsy for me.
This is the thread that gave me the idea and as best I can tell you are the man with this stuff.
