Mash efficiency is presented in BS as a blended conversion efficiency and lauter efficiency. Many brewers watch gravity in the mash tun before starting lauter/sparge. Beersmith seems almost designed to support this use but not quite there.
I would set the conversion mash target at 100% in settings and present under "mash efficiency" estimated (based on 100% conversion) and measured pre sparge mash gravity. Then total mash + lauter efficiency would show up under volume and gravity in boiler.
This would help brewers diagnose low mash efficiency. We see questions from brewers with low mash efficiency all the time on homebrewtalk and everyone piles on with their favorite fix...problem is they rarely even know if their issue is conversion or lautering.
