I got briefly excited at the text editor, but it's just for 'function nodes'. I do understand that it's essentially the opposite reasoning of why Node-RED exists in the first place, but I really want a sane version-controllable file describing the configuration.

Essentially, I'd like to be able to use NR as primarily a viewer (probably also editor) of a 'source of truth' config file.

As it is, at very least nonsensical node IDs make it.. not impossible, but not useful beyond as a backup; no meaningful diffs.
