In non-split-touch-controls, the white circle that appears and fills up as you mine a block, is too big. Before 0.7.3 it was about 1 inch (diameter) and could be adjusted with 'd-pad size' according to preference. Now - in 0.7.3 - it is about 3-4 inches (diameter) and CANNOT be adjusted with 'd-pad size'. This is distracting having the huge circle in the middle of the ipad screen every time you mine.
