Currently, although it is possible to select all nodes in a Blueprint and copy them to a text editor, this operation only applies to the current Graph, and a Blueprint may contain multiple Graphs, making this process cumbersome.
It would be great to add a feature that allows exporting the entire Blueprint as AI-friendly text (e.g., JSON), as well as importing a Blueprint from text.
This might sound a bit like self-promotion, but I happened to build something along these lines for my own use. If you like it, I’d be thrilled if you considered buying it.
