'Lighthouse' mode for ComfyUI — click any node and the rest of the workflow lights up by graph distance. Direct dependencies red, then orange, yellow, green, blue, violet.

"Lighthouse" mode is a ComfyUI feature that visualizes workflow dependencies through color-coded highlighting based on graph distance from a selected node. When a user clicks on any node, direct dependencies appear in red, with increasingly distant connections displayed in orange, yellow, green, blue, and violet. This visualization tool helps users understand and navigate complex image generation workflows by making node relationships immediately apparent.
