When using many LINK nodes, it is more and more difficult to know which Link-OUT or Link-CALL sent a message to a Link-IN node. Especially if a Link-IN can be called from multiple OUT's or CALL's.
To be able to trace where a message to a Link-IN came from, I suggest adding an option to the Link-OUT and Link-CALL nodes to send the name of the link (and this must then not be empty) as a fixed message property.
Something like:
[boolean] Option: Add Origin to Message
which would then generate a property: _linkOrigin {name of link node}
Link-IN nodes would not need to do anything with the property, but this would make debugging a lot easier!
I'm not sure where the right place to ask is, but I would also like to know the status of an earlier FR:
