What a find! I am a digital course creator and a coach for course creators. I'm happy to say that I won't be spending money on Post-It Notes anymore. Poda allows me to set up mindmaps with certain variables (eg. In course creator, I have Learning Outcomes, Modules, Assessment and Methodology), and then, I can change view to a Roadmap view.

It doesn't sound groundbreaking, but it is for me. And at the cost, it's a steal.
