In the example below (all empty cases, with Case 0 connecting the Case Selector to the output tunnel), it is not possible to use the Linked Input Tunnel >> Create & Wire Unwired Cases action:
This menu is only accessible when the input is passed into the structure via a tunnel:
Now, I know that this menu is called "Linked Input Tunnel" (why not "Link Input Tunnel"?), not "Linked Input Tunnel or Case Selector", but it strikes me as a missing feature (I did not say bug).
Comments?
