This is a helper extension for ComfyUI that assists with node connections.

When you hover over a node with your mouse, an icon appears.
- Left Button: Clicking this button connects the closest available output from nodes on the left side to any empty input slots on the node.
- Center Button: Clicking this button duplicates all input connections of the closest node.
- The duplication feature only works for matching slot names and does not disconnect any already connected connections.
- Right Button: Clicking this button duplicates all connections of the closest node. (However, this can only be used when all inputs and outputs are empty.)
