Estimated post-sparge gravity

When doing partial mash it would be helpful to have an estimated post-sparge gravity. This way one could modify the DME/LME additions either up or down based on whether or not they hit their mash efficiency.

I'd like to second this request. I brew a few different ales which use sugars added during the boil, but these seem to be factored in the Mash Estimated Pre-Boil Gravity numbers. This means I have to zero out my sugars in the recipe to see what my target gravity will be before the sugars are added.

Maybe a checkbox for ignoring sugars and extracts could be added as a per-recipe option?
