Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
More than just chests.
Major bug in the mod, beware! If you change the chest channel while there are items on the new channel, everything gets erased and all items are lost.
All items get lost just by adding a new chest to an existing channel as well. Which is a major flaw and makes the mod basically useless if have any plans to expand a network using existing channels. Needs to be fixed ASAP.
