i really like the inventory and shopping list functions. It would be a lot easier to prepare my shopping list if, as I add the recipe to my shopping list, my inventory showed "available inventory" from which you could reserve some or all for the current recipe. For example, with 8 oz of crystal 60 in inventory, adding a recipe that calls for 6 oz of crystal 60 to my shopping list could reserve 6 of the 8 oz for that recipe. That way the next recipe I add to my shopping list that calls for crystal 60 would show 8 oz in inventory but only 2 oz available. Right now I have to keep track of that mentally or on paper. Having that would facilitate using my shopping list to manage the gap between my brewing requirements and my inventory, minimizing the excess inventory, without a lot of thinking. You could, when converting a shopping list to inventory, release the reserved amount. Really enjoy using these tools. Thanks for creating them.
