Depth-First Search Upgrade

The Depth-First Search Upgrade is an item from Extra Utilities to aid the transfering of items. With a Depth-First Search Upgrade, a transfer node will now search more intelligently and if it reaches an intersection it will explore down each route in turn returning to the intersection once all options have been exhausted. This if only one chest in the image had space for items, the node will find that chest within one pass.
