It's pretty common to switch back and forth between a screen and the flow it belongs to. 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 is connected to others within a flow, connector indicators will appear on the left or right side of the canvas, depending on the direction of the connection, while you're viewing the screen.

Hovering over a connector indicator reveals a pop-up with the name and thumbnail of the connected screen. Any labels added to the connectors will also appear in the pop-up, making it easier for your teammates to understand and follow the intended path.
