This is one of the main things that makes visual scripting more powerful than regular C# and justifies the performance cost of using the asset, so I think it’s worth making it a part of a regular workflow. Both a global toggle for all graphs and a manual save button for individual graphs would be nice to save changes made in Play mode. The current JSON export/import is too cumbersome for quick, small changes to the logic and it breaks the flow of working on the logic in general. This change would speed up the workflow considerably.
