Leader or participant in a started loop

On the start page there are started loops. They look different depending on whether you are a leader in the loop, or a participant. A loop where you are a participant has a progress bar and a play button, and the ones where you are a leader have a button that says To Leader Panel. If you click on a loop where you are a leader, you will come to the preview mode of the loop. If you click on a loop where you are a participant, you will come to work mode, where you can   communicate through the nodes.
