Would be great to have the priming calculator work out the amount of water to mix with the sugar in order to maintain the same ABV (or increase it if brewer chooses).
This: http://www.woodlandbrew.com/2012/12/abv-from-priming-sugar.html explains the issue and provides the equations needed.
Would make the calculator more complete and as far as I can see would give BF an advantage over other calculators and brewing software packages.

Thanks,
