Connectors can be customized with different styles to represent different types of connections between screens—they can have different colors and either be solid or dashed, while they can have arrow or point ends.
To customize a connector, you can select it, and the style options will appear on top of the connector.
Just to give some insight, our users tend to use the red color to indicate error paths or the gray color with the dashed style to indicate paths that go backward in a flow. The connector with arrow ends can also be used to specify the endpoint and the direction of the flow.
💁♀️ Flows support undo for all actions! Simply use the shortcut ⌘ + Z / Ctrl+Z to undo the action.
