I second that request. I requested this a long time ago and the response was that it would take a lot of work to get down to every detail of a brew's cost. I think at least a simple cost accumulator could be added to the recipe builder, each ingredient could have an additional field next to it...

It would be nice to have a quick inventory check in the recipe tools so you can do a quick check to see if you have everything on hand before brew day. When my inventory gets large or a recipe has a lot of different ingredients checking manually can become cumbersome. Also it would be nice to...

I think it would be cool if you could assign prices to everything in the recipe tool based on your LHBS prices, then have it approximate the cost of your batch. It would also be nice if this data was used when the batch was brewed to calculate the approximate cost per bottle.
