Please, please, please put in support for the D-pad! In the 'Details' screen at a minimum. It would be SO much easier to page through the residents with that. (I find that the 'forward/back' arrows on the details screen are too small, and really inconveniently placed.) Right/Left to page to the next/previous villager in the database, Up/Down to page through the preferred skills, with the center button used for "Done"

Another use could be, in the "Villager View" screen, to focus on the next villager in the pressed direction, with the center used to jump to the details screen. When villagers are clumped together, and won't/can't move apart, selecting the exact one you want can be ...difficult.
