I was surprised & disappointed that a setup like this doesn't grant access to all three barrels, like most other networked storage systems do.

I like the simplicity of this mod, but the fact that there are several blocks that seem to connect inventories in slightly different ways is a little confusing. It would be nice to unify those connection features under one thing: cables.

The inventory cables are designed for long range one to one connections. Use the Inventory Connector and Inventory Trims to connect them like this.

I guess in that case it'd be nice to have some indication of that in game. I was pretty confused by it.
