When using barrels, the amount of them can get quite big. This has implications for bases, as they need to accommodate all these barrels, as well as performance, that (seems to?) start to fall when having a lot of barrels around.

For this, I suggest adding a Barrel Drive. A Block that can store Item Barrels and act as a barrel connector for all the contained barrels. For the crafting recipe I'd suggest using a Barrel Connector (for the connector functionality), Antibarrel(place to "store" the barrels), and some items that make it seem like a typical recipe (some iron ingots, maybe a netherstar).
Something like this

or this

This would improve the following:

• no more giant walls of barrels, potentially tanking fps
• possible performance improvements, since barrels are inside barrel drive and don't stand around
• cleaner storage solutions
