See who is in the page, and where they are typing
The editor bar shows everyone in a page, each with a live dot and the field they are in.
When someone else opens the page you are working on, they appear in the editor bar with a live dot, and you can see where they are typing. Changes appear as they are made, so two people can work on one page without writing over each other.
While reviewing or suggesting, changed and suggested blocks are marked on the page, and the bar steps through them one by one.
