I'd welcome and find the following extremely helpful.
Ability to increment/decrement in different amount than inventory.
For example I have 11 lbs of some grain. I use 2 oz. I want the ability to, in the new inventory control, put -2 oz and BeerSmith will properly decrement.
Likewise, I have 11 libs of some grain. I purchase 8 oz. I want the ability to, in the new inventory control, put +8 oz and BeerSmith will properly increment.
