Remove unnecessary references

[pennatula]

Identical references on interactions and anchor points seem repetitive. For cases with references on one or more interactions leading to an anchor point, the anchor point also lists the same references, which makes the pathways look busier than necessary and doesn’t really add any information. Is it OK to skip the references at the level of the anchor and keep them just for the incoming interactions? See the attached for an example. Note that I dragged the horizontal interaction (with the anchors) up a bit to show the references clearer.
