I'm all in. I love the cloud approach. You have almost everything I need, and it is accessible from wherever I am brewing or discussing recipes. I use your tool constantly.
But, I find that I still use Martin Brungard's Excel spreadsheet for calculating acid additions to the mash.
Therefore I would be most interested in a tightly integrated water, grist, pH, and mash acid addition calculation as part of the front page recipe sheet. Perhaps it could live in the Mash Guidelines section where it has water volume and the grain bill right above.
Great tool. Thanks.
Cheers.
