Strike/infusion temps will be automatically calculated going forward, so no need to seperate calculators or anything like that. Also mash thickness and strike volumes, and batch sparge volumes as well (if your equipment profile is setup to do so and you enable it in the recipe).
That's the idea is to have all of those recorded and supported directly in the recipe builder, and measurements/volumes that occur on brew day should be used via the brew session event logs.
We're open to alternative feedback like that, if you want to record the volumes/measurements via the mash guidelines that's something we can take into consideration but if so we'll likely need to scrap the existing mash guidelines and reproduce the new format from the recipe builder so they're mirrored.
