Wow..I'm disappointed too. Windyty 3D was the only app I could find that used to allow me to 'chase' airflow to/from the poles when mixed with the altitude parameter. It was an absolutely amazing feature that you should have promoted over the 2D version. We are not a flat Earth society after all ! ;-) Please think about bring it back and making it easier to find. It was so hidden that most people would not have just found it. Likely the reason it was used so little. It should have been the default.
