Oh I guess I alluded to it but did not declare/describe it. Essentially an embedded library view that take json from document tags to build instances on a view canvas and a SVG background. It's still a work in progress.
One major enhancement would be a way to convert components in a coordinate view to items in a view canvas array and back. This would allow drag-and-drop embedded views to build a diagram, then convert to a view canvas, instead of today's painful workflow of hunting and pecking modifications within the view canvas instances. Convert embedded views to view canvas instances?
