> Could you sort the JSON before saving so the output is more stable and diff-able?

Jsons are definitely diff-able but it's the difference between a change that changes the logic of the flow or a change that is purely visual and has no affect on the logic of the flow that is hard to distinguish by just diffing the JSONs.

Remember the Json contains location of nodes and labels of nodes as well as logic of nodes - if a label of a node changes it doesn't affect the flow logic or how it works.

So if the value of an 'x' changed, that means the node moved along the x-axis. Did the value of 'func' (function value for a function node) change, then that is a logically change. Now what change is important if you only looking at the JSON. So you need to remember that 'x' and 'y' are visual, 'func', 'tmpl', 'rules' are logical. And what is important for each node isn't the same across all possible nodes ...

Exactly that's why places like GitHub would need a lot work to support visual coding in proper way. Diffs would have to become like image comparisons that line-by-line diffs.

And that is partly why visual coding has taken off - the tooling isn't available.
