How do I quickly merge a new node in between two already existing and connected nodes?
Right click the connector and “Insert” is the main one.
But you can also create then remove a portal through the P menu.
You can also do this by right clicking the first node > insert > chokepoint then Ctrl Q to change it to any other node. If you already have the node you could copy it’s properties in its right click menu then paste them in the inserted node.
A few different ways really.
