Scene editor: show node usages / dependencies / references to this node

[hsandt]

I thought it was proposed somewhere but I can't find any thread.

Built-in resources contextual menu have Edit Dependencies and View Owners. I would like something similar to find which nodes in are referring to a certain node in my scene. This would help me identify which references I will break when removing a node, or which event is triggering a certain effect.

Example: right-click on Prop node > Show references to this node > displays a pop-up listing other nodes referencing to this node, with a preview of the script + member name referencing it.

While it may be hard to determine with dynamic string path loading, it should be doable with @onready vars with fixed $Paths and @export-ed node members (which represent 99% of my cases).
