No further explanation needed! Edit and see your changes appear for your teammates in real-time. You can also see what nodes your teammates are currently working on in both the script and model views.
Commenting works in both the script and model views.
By clicking on the comment icon on any step (in the script view or the model view) you can leave a comment on that specific node. You can also switch over to commenting mode in the model view and click anywhere in the canvas to leave a comment.
You can see a list of all of the existing comments in the script view when no steps are selected or in the model view when in commenting mode. If a comment is attached to a specific step, you can click on go to source node to go directly to the comment.
