As is usually/often the way, my questions end up revealing that there are capabilities of Vuo that I am not yet aware of. Thanks, hidden cables serve as well as I was proposing. A nice touch would be if the cable was made visible if the nodes at either end are selected.
How do people handle sub-composition when it comes to distributing compositions. For example, I might have a number of subcompositions I've created and use regularly, they are located in my node library. When it comes time to pass the composition I'm working on to others it is easy to miss a required subcomposition ... or just time consuming to find them and test.
Suggestion, a new save or export choice which has an "include sub compositions" option.
