That's what I would hope to see ... the ability to sort of visually code a "base code" (several nodes strung together that do a job) that could be grouped into my own custom node that can then be re-used in various ways.
BTW - I think I already know the answer to this, but I suppose it's best to ask - does the visual coding system allow me to create a piece of code (say, like in the video, that opens/closes a door) and then I can use it multiple times with various doors, even if the door is different? So, if I have 10 different doors, can I attach visually code the door code once and apply it 10 times, tweaking it for each door as required?
Lastly, and somewhat related, does Skyline allow me to save prefabs (models, lights, and code, etc.) that can be saved as a single unit and brought into Skyline as needed? So, for example, could I create a door, door frame, attach the door code, and save that all out as a single prefab so I can re-use the door over and over again? I am assuming this is included (and may be what your GO objects are).
