It doesnt let you draw very small lines. You have to zoom all the way in to make a dot or small line. If you were writing an i, for example, you have to zoom in 300% to make the dot. Or if you were drawing someones face, you have to zoom in to make details. But then it ends up putting random dots and lines when you didnt mean to. This is really annoying.
