The frame rate and delay on a tablet is horrendous. On some slides I can swipe down and on others I have to swipe left, with no indication which directions are possible, some times I don't know of i can't swipe down or if the page is just loading. Is the presentation linear ot is it supposed to be a 2d grid? If you go to the right then down then left the left will go up instead of actually left.
