For the warnings in a Revit file: I’m aware of how to suppress them and have done so with addins quite a bit. However, some are in fact not dismissable. In dynamo, it is very difficult to subscribe to events, so I won’t be spending time implementing that kind of workflow in Dynamo nodes as it becomes unpredictable very quickly. (As you are seeing with some of the nodes you are using now)
In regards to the orchid nodes. My nodes won’t be compatible with his as I am storing the documents in a more stable way. See this post for details, Copy Views to Document on file
If you are using any orchid nodes, I would say you stick with that package and not mix the two. If you have issues with those nodes that would be reported through his GitHub.
