Bill, we all struggle finding the up down and left right buttons on flat screens. I've made a template which fits over my screen which gives a positive location but seeing that you are considering improvements It seems to me that if the movement buttons were healthy thumb sized on an iPad and one at each at the four corners of the screen and everything else was arranged in the middle at the bottom below the horizon then it would always be possible to find the movement controllers (which are a most important function in the dark) without the need to look down. Can this be incorporated in any new version? Jeff.
