Brewhouse Efficiency Button?

In the Beersmith article, "Brewhouse Efficiency for All Grain Beer Brewing"http://www.beersmith.com/blog/2008/10/26/brewhouse-efficiency-for-all-grain-beer-brewing/, a "Brewhouse Efficency Button" is mentioned. The line says, "In BeerSmith you can click on the “brewhouse efficiency” button in any open recipe to perform more detailed mash or overall efficiency calculations."

However, in my Beersmith (version 2.0.65), I can find no such button - either in open recipes or anywhere else. What gives? Am I missing something?

Thanks for your answers.

I believe that was in v1.4, and given that Oct 2008 date of the article, that seems to be the case. 

Most of that info is on the Mash screen now.

Ah, that explains it. Thanks.
