Something like that that would seem perfect thanks ^^
Just making it work in the same way the BBParam works would go a long way, especially for designers.
In the example below because the ValueInput is not fielded nor connected I would expect it to be red like the BBParam is.

The red would disappear when the connection happens or if the field has a value:

Also it seems important that if a Required field is not set in the node then the node should also show up a red sign, similar to what behaviour trees are doing:
