Fix the 4s

I love this app. I am always pleased with the picture when finished. I would give it 5 stars but for a couple of issues. I finally figured out why the 4s always have a white dot in the middle of the number - the 4 is enclosed. I think this would be an easy fix to change all of them to an open 4. Next is the difficulty coloring some smaller areas. I dont mind it only colors half the space but hate it when, no matter how many times I hit it, it will not color the rest.
