I imagine this is how Jake Rodkin organized his.
Virtual Console
Indie Games - VVVVVV, Gunman Clive, stuff like that
Demos
Eshop - Basically Nintendo eShop exclusives
Online - that ATV game
Games - the bundled games that I never use
Applications - sound recorder, photos, Colors 3D
Mii Stuff - Streetpass Plaza and Mii Creator
Entertainment - trailers from the eShop
Stuff - the health and safety thing and the Nintendo Zone app
Then I have eShop, game card and settings in the column just off the side of the screen.
I see what you did there, pretty neat
