Flow Manager module for node-red
node-red-contrib-flow-manager (node) - Node-RED
Looks super useful for managing and distributing code in an organized way (instead of having single flows.json). But what makes me hesitate trying this is it hasn't been updated for several years and people are reporting security issues due to old outdated dependencies. It looks dead and no longer maintained. Does it still work? I can only imagine how brittle it is if node red changes something in a future version.
It would actually fix git diffs cleanly and also help distribute subflows since everything is in individual files.
