In case you are interested in improving the drag-and-drop usage:
There are a lot of connections which look like they should work, but don't - such as patch panel to patch panel. On the other hand, it is possible to connect a single LC connector to two splices at once. There doesn't seem to be any way to unmake a connection. Overriding existing connections sometimes works, but sometimes doesn't. The tube nodes don't have a clear drag-and-drop point towards a cable. By default the tube nodes have a colored edge matching the incoming tube connection, but this edge color doesn't change when you drag a different tube from the cable onto it. The cursor sometimes wrongly shows a "+" to indicate a possible connection, such as trying to drag from one tube exit to another. It is somehow possible to connect two cable tube exits to a single tube node. It is somehow possible to connect a cable tube exit directly to a splice node.
Those probably don't matter all that much if it is almost always auto-generated, but considering the amount of weird behavior it might perhaps be better to disable the edit functionality for now?
