The ability to have multiple people participate in the same meeting, without one person interrupting another. It is easy for everyone to see who's speaking and what they are saying, even if you're not in the room. I think it would be helpful to have some way of making your screen private when you need it. I use Jell primarily as an internal communication tool within my team. We set up our meetings so that there can be two different types of participants - those who want to interact, and those who just listen. This helps us manage two separate conversations at once.
