Hi There

This goes back to a previous [pain point](https://discourse.nodered.org/t/link-call-nodes-visually-showing-the-connections-to-link-in-node/81396) and that being the visual connection between a link-call node and its corresponding link-in node.

Link-in and Link-out are visually linked and it's easy to navigate between the two, this is unfortunately not the case with link call nodes. And this is a pain point for me so I came up with a !!hack!! solution using green dots:

![linkcall](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/c/3c148874ae91377aa1ddb6249301eb9657901cd3.gif)

This is not the way it should be done but I needed something _now_ and that was the simplest thing I could think of. The green dot on the link-in node brings the clickee back to the original link-call node (i.e. the first green dot clicked). Also, to remove the green dots, switch between flow tabs.

It can be tried out [here](https://cdn.flowhub.org/?fhid=c520d9da20ad7f1d&t=0&sb=Introspection) and the [introspection package](https://flows.nodered.org/node/@gregoriusrippenstein/node-red-contrib-introspection) contains the functionality.

Hope it helps.

Interesting idea.

Thanks for putting in the work on it.
