Similarly to how unreal.js and unrealenginepython could run in editor context.

Would require re-wrapping node component https://github.com/getnamo/nodejs-ue4/blob/master/Source/NodeJs/Private/NodeComponent.cpp into a re-usable unit with editor runtime. Optionally a component with an editor tick toggle. Unsure of best UX, use case examples from users requested.
