The current register event callback node is allowing an easy way to handle ActiveX and .Net Framework events. This node is also very similar in appearance to the property nodes, yet it does not have an insert (Add Element) or remove (Remove Element) function available in the context menu. Since the property nodes, and also the named (un)bundle nodes are having this implemented, I think it would be nice to have these easy to access functions instead or having to grow the node, change all the elements below the one that we want to insert and rewire everything.
One downside of this idea is, that it will throw the wires a little further away than the upper mentioned named (un)bundle and property nodes do, since it is a 3 terminal height element.
