Currently, if you copy + paste a figjam flow into a Design file, the Connector Lines stay fully functional – they stretch and adapt as you move their origins and destinations around the canvas, and you can move their origins and destinations to your frames, components, etc.
I’ve been using this to show user flows within my UI designs, not only for ease of sharing with other teammates (no need to give in-depth walkthroughs), but also for easily identifying missing states within a flow.
It would be great if a) the Connector Line was added as a tool to Figma Design, or b) basic lines and pen vectors had the option to act as connector lines – attaching to anchor points on objects and components, scaling when the endpoints were moved, and able to be adjusted with mid-line handles.
