It would be awesome if you could link bags to inventories. So say you have a bag to that auto-pickups whitelisted ores. You can shift right click that bag to a chest, or crusher/furnace and it automatically gets sent there.

You just mean like if you right-click it to a chest, all the stuff in the bag goes into the chest?

That would probably be more balanced. But I was thinking at first, the items get sent as you pick them up, if you bind it to an inventory. Like an ender bag sort of.

Noo, I'm not doing that, that's way cheaty.
But I'd be up for the put everything into a chest thing!

Could you add it for furnaces and other things as well that uses IItemHandler, and it remembers your inventory at the time you right clicked? Like a furnace can only accept 64 items, but you have 4 stacks of ores in your bag. You shift right click the furnace and it adds the first stack, and the rest as they have space? There would need to be a way for the items to not be taken out of the bag during the process, or if you, it cancels the event.

If not, then chests would be more than fine. I could just create a chest next to machines as a buffer.
