First thing I noticed was the awesome node ui and went to your package.json to see what library you used... nope, you made your own, lol. Awesome! I've been looking for a good react/js node-graph library with a lot of customization around nodes/edges and good hierarchical auto-layout and the best I've found so far is https://reactflow.dev/ but some of the features I need are behind a pro-license. I hadn't considered trying to write my own, it doesn't seem like a trivial task, lol. Anyway, awesome work on this app!
