Would love to take a deeper dive into what you feel would improve your experience.

I'd be happy to discuss, we'd need to figure out a better communication path but that's doable.

Some quick wins: - make the workspace persistent so you can resume what you were doing the last time you visited - the Swagger UI does this, not sure how but I suspect browser side storage. This might be easy for you. - more user feedback when you add a new block to the workspace. For example I kept clicking items from the toolbar wondering why nothing was happening until I finally realized a buttload of new objects had appeared in the workspace but weren't highlighted enough to notice them.

Some kind of auto-arrange would help a lot, starting with a pile of rectangles that you have to manually drag around to have any chance of making sense of it isn't ideal.

Graph diagrams look great but they fill a screen VERY quickly. There has to be a lot of thought into how to make the boxes as small as possible so someone can get the overall layout of the land, but can quickly access any details.

And the harder stuff would be some kind of assist dialog when you add a new toolbar item (I'm NOT going to suggest AI here, maybe just a dialog box which lists mandatory items and them other items in the order from most to least common). I understand this is tricky because you intend to support all API versions.
