I am very happy to see your progress. I fully support your idea that we need a separate section for nerds who make their own worlds, because. they are often lost in the stream.
I'm very interested in a technical point, how do you draw the polar regions? I understand you are using vector graphics. Save the process, reproject, and then when you're done and you've inverted the map back, do you draw again with a distorted pencil? Is there a quick way to convert polar caps back and forth while still being able to edit layers in Photoshop or Illustrator?
