Woah- you made a whole node editor/visual programming engine, that's crazy!
I feel like I was craving a way of removing connections between nodes, but it didn't detract too much. I'm impressed you were able to pull this off, have a whole UI, and actually make it look/feel good in such a short amount of time, really nice work mate!
