In some projects, we rely on Link nodes quite heavily. With the editor changes in the recent past, it already improved a lot, to understand the connection between nodes (especially through the dashed wires).
As of right now, the dashed wires are only visible when selecting a respective Link node. It would be quite helpful if there was a shortcut to display all dashed wires in the current flow (e.g. by pressing Shift or Alt).
If this conflicts with existing shortcuts, it might also be helpful to expose an API to toggle the visibility of those wires.
