i find several time follow a cable to check what it is connected to. I think could be a useful upgrade a shortcut that automatically follows the cable showing the connected node in center of the window.
Like: ⌘← show the node where the cable originates inputting in the input pin of the selected node.
And: ⌘→ show the first node receiving data form the selected node. Following + right arrow shows eventual other nodes receiving data form the same node.
