If the Wii U is as powerful as some people are claiming and it can handle FFXIV and you decide to port it over to the new console can you please, please, please take advantage of it's controller. A few ideas of what I would like to see are:

Action bar and macro's on the controller screen for quick touchscreen access.

Button to bring up the map on the controller.

Button to switch controller screen to a keyboard to type messages.

Ability to drag chat logs and other widgets onto it so I can clear some clutter away from my main screen.

These are just a few quick ideas I am sure there are many other nifty things you could think up to do with it.
