The Flash "editor" software was a work of a genius. The combination of vector graphics editor, symbol library, layers, animation tools and code was super powerful yet super approachable at the same time. I have learned AS2 just by toying with the examples. Over time I learned AS3, then HTML and TypeScript, in this order.
One more shout out to the vector graphics editor - the way you did boolean operations with shapes based on their color has not been bested since by any other editor.
Shapes of the same color are added to a single shape, shapes of different colors are extracted from each other. Lines (of any colors) can (but don't have to) split shapes. A simple rectangular selection with mouse can add a bezier point to a shape, simple aligning of the bezier point with its curve will erase it. If you know how to use the editor is is super efficient.
