Second edition. I’ve added the ability for multiple inputs and outputs and correctly renders the connections. Module creation and connection creation are all still manually called at the moment. When you create a module, you specify the number of inputs and outputs. When you make a connection, you specify which modules and which inputs and outputs. You can see there are some strange rendering problems when the right-hand modules are moved behind the left-hand ones. I’m working on that too. It’s better than it was though.
