This. Topia is currently designed to accommodate breaking up into groups of 10. For one-on-one conversations there should be a function to either 1) Expand a single video chat without going into broadcast mode or 2) a dedicated "conversation" layout that expands all active video chats. Topia is great for navigating into a conversation but once that 1:1 conversation starts 95% of the screen is wasted space and it becomes a mediocre user experience compared to the alternatives.
