I really like the idea that I could determine the path of the bokeh with my finger, but the app puts the shapes around my finger as well so there is no precision to this implementation. Also, the size of the bokeh are larger than I need / want but there is no size control. If the devs allow for more control of the path and size then this would be at least 4 stars. I look forward to updates and a chance to give a better rating.
