I spent a year working on visual versioning for NodeRED flows because that was the first thing I felt was missing with NodeRED. The result was FlowHub.org which differentiates between visual changes and textual changes. Which was my main focus. There is no visual concept for merge conflict or similar but at least versioning is far simpler since comparison between versions is much simpler.
