In a brew session, when my mash efficiency isn't what I had planned for, I'd like to have have an easy way to adjust my wort before I begin the boil. I know there's a boiloff/dilution calculator, and that's certainly one way to solve the problem. Sometimes, though, I'd rather just add some malt extract to make up lost gravity points for poor conversion, instead of lengthening the boil.
Currently, I use this calculator for determining how much malt extract or sugar to add: http://www.topdownbrew.com/gravityAdjustmentExtract.html. However, it would be nice to see such a calculator integrated into Brewer's Friend and linked from the brew session page, just like how the "priming sugar calculator" is linked directly into the "amount packaged" section of the brew session page. As a bonus, the calculator could have fields like "current volume" and "current gravity" or even "desired volume" and "desired gravity" pre-filled from the recipe attached to the brew session.
