As one example of how its helpful…
If I have an event in blueprint x and that event only gets called from blueprint y. I leave a comment there that says “this gets run from blueprint y when this thingy happens.” Would be nice if I could right click and add link then select blueprint y and hit ok for the root… or get a dropdown of all events in blueprint y and select the specific one that calls this function/event (or any other events I think are relevant to link here). Which creates a clickable link to bring you straight to the event thats linked, similar to how clicking the parent actor in the top right opens the parent root"
