A combination of all the other gadgets into apps on one thing (like the Poketch.) Thus, it would have an online app (C-Gear), apps for the Pokegear (ex. phone, map etc.) and apps from the PokeNav (ex Condition, ribbons etc., though it is unneeded if they just show those things in the Pokemon stats screen) and all these things would be combined onto the Poketch like device seen on the trailer, with other apps that were on the Poketch. And, I want the menu, registered items, and running shoes to be on the touch screen as well. To save space, the menu would only be icons on the side (unless you press X which opens it up with text). For example, on the left side there will be an icon of the Pokedex, a Pokeball (for Pokemon), and a Trainer Card, while on the right would be a bag icon, a wrench icon for options, and a recording icon for saving. And since these would only be icons, there will be more space to show apps in the middle of the screen. At the top (pf the bottom screen) it would show date/time, battery life, and the Apps' name, and a button that allows you to switch between apps instanly (rather than pressing the "Next App" button.) And finally, at the bottom would be your registered items and the running shoes.
That's pretty much my dream for what the bottom screen and "Gadget" should be for this Gen.
