That’s an interesting idea, but I don’t think it’ll happen. Any new feature means increase in maintenance, and CSIDE is a solo project. Besides, it looks like there’s a big update coming to CSIDE.
Personally I’ve never been a fan of the mind mapping way of coding like that of Twine. It can get too convoluted. However, I think block-based coding would lend itself pretty well to the Choicescript crowd.
