Request: Gaming / Retro Platform Categories

Hi, I love the new Platform Categories in Big Box mode. What I ideally would like to have is big box boot into Categories mode with just the options for gaming (all my modern windows games) and retro (all the emulation goodness) I would much appreciate if this could be done by adding new Categories or a way to add/edit them by the user, Thanks and keep up the great work!!
