Hey hey, Congratz on the kill :). How did you find playing on your phone?
Just want to say a few things. Yes we have NOT touched the Interface layout as of yet. We have some internal prototypes floating around which we are refining and will release at a later date.
You can move the Interface around the same as on PC. The only problem is that you need to be very accurate with your clicks. As it is your LIVE account you can head to the PC and arrange your layout, then when you go onto mobile it will remember it :) (joys of cross platform).
Any more questions, just reply and i'll try to answer them if I know how ;).
