If you're eager to start arranging all your 3DS content into folders – and we're not mocking you, we were thrilled to start consolidating – you can start tonight. The system update
enabling custom folders on the 3DS home screen is available now in North America, slightly ahead of its April 25 release date.
The update also brings a redesigned eShop interface, which divides shop segments into two rows on the screen. That's all we've noticed in the few minutes we were looking around (at our beautiful, compact home screen, mostly).
