It's pretty common to go back and forth between a screen and the flow it lives in. Once your flow is set up, anyone viewing it can double-click on any of the screens to get more details—such as comments and specs.

If a screen has connections to other screens in a flow, the connector indicators will appear on the left or right side of the canvas (based on their direction) while you're viewing the screen.

When you hover over a connector indicator, a pop-up will show the name and thumbnail of the connected screen. Labels you add to connectors also appear here, making it easier for your teammates to choose the path to follow.
