Item Network Terminal

Terminal allows you to see contents of several chests, search them by name, and also to retrieve N of some item (e.g. 20 Oxygen) or "all except 1" of some item, as long as this item is stored in one of the chests.

Wiring
Connect your Terminal to of Repeater, and then connect multiple Storage Bridges to  of that Repeater.

Limitations
Terminal doesn't work with far away chests (outside the player's view). Having Watchers near out-of-screen chests DOESN'T HELP WITH THAT.
