I love diagramming, but I genuinely don't understand how people can use these wonky looking tools. It looks off, I had to make my own[1] to create something that's easy to use and looks good/normal. [1] https://grafly.io
Questions: 1. Will you be making the source code public? 2. How to export the JSON for SCM, then re-import for updating/maintenance?

In the upper right there is an import/export button that could be used for this. It's stored in localstorage so you could also dump that to wherever you like.
edit: added link to the repo in the about modal. edit2: added import export of the entire localstorage entry on the bottom of the diagrams(left) panel.
