XpanXn: Chat designed for how conversations really work

Hey everyone, my name is Peter and I developed XpanXn ("Expansion") after wondering if instant messaging could better mimic real-life conversations if it were designed more like a mind-map. XpanXn is an instant messaging app where your conversation is not limited to the vertical direction; it can expand in the horizontal direction to isolate different conversation topics being discussed simultaneously. Along with redesigning the dynamics of instant messaging, XpanXn also offers better privacy with no third-party data mining of your messages. You're the customer, not the product. My intent is for this to be a minimum viable product. There's quite a bit of refinement needed to get XpanXn to realize its full potential and match the features we've come to expect from instant messaging apps. I hope you'll give XpanXn a try -- no account needed. I'll be standing by for the next hour or so to answer questions, and feedback is much appreciated!
