[Component] Display warning when some port is unused
Scenario:
- create a component
- add a port “Blah”
- create an automaton in the component which does not make use of the port
Expected behaviour of the feature:
- display a warning stating “the port Blah is not used, that is probably unwanted”
Current behaviour:
- nothing
Might be too invasive. In such a case would be nice to add this as an preference/option.
