My thoughts however were along the lines of a simple embedded flowcharting tool for inclusion within the Flowcode project source, enabling simple high-level charts to be created/presented/discussed potentially in advance of code development, particularly for collaborative discussions with non-FC users, and which wouldn't have any necessary relationship to project source.
The latest version of Flowcode (v11.0.1) was released today and this includes a new feature called "Blueprints" which hopefully achieves what you want. More information can be found on this wiki page.
