The Recipe Editor gives the percentage by weight of each fermentable in the recipe. For example, if I made a trippel with 13lbs pilsner and 2lbs sugar, the "fermentables" portion of the calculator would report that the fermentables comprise 86.67% pilsner malt and 13.33% cane sugar. It does this regardless of what the "efficiency" is that I set for the recipe. I'd like to see the percentage of each fermentable as a function of its extract contribution. Ideally, I'd like to be able to switch between which percent measurement I see, or be able to see both at the same time. I know there's the "OG" statistic underneath each fermentable, but I'd rather not have to do the math myself summing up all these values then dividing the OG of the fermentable in question by that number. This would be immensely useful when creating recipes that mash only some of the grist, using malt extract or sugar for the rest of the fermentables. Excuse me in advance if this feature is already available somewhere and I can't find it, or if this feature request is a duplicate of another one. Thanks for making such a great product! I spend a lot of time here.
