Create Systems mapping tool
A big challenge in design is the impact of unintended consequences. Systems mapping with causal feedback loops help you see the impacts of a system in one space. Your tool is very close to this- if you add causal system loops and a few other systems thinking/mapping tools, you would have the best software in the world for this.

Just to be clear, are we talking about some sort of flow-chart ability? I'd love for that to be added.
