I typically agree with the "no sub-boards" with a few exceptions.
If you browse the other sites, and the sister to this one, you'll find a LOT of the same queries posted over and over, which get's tiresome to read through if you're looking for something.
I'd "like" to see a "suggestions" sub board, as while we use the instinct more and more, possibly a better way to do things with it. e.g. being able to manipulate icons/screens/info from computer, or instead of tap here tap here tap here make it like a macro, where you tap once.
possibly a generic sub board for the questions, specific or similar to:
Main screen questions, Fun screen questions, Web screen and so on.
