Most everything is going to take up some real estate somewhere. My recipes already run over into two pages, particularly after I've brewed a recipe a few times and have a few notes built up. I still like the idea of putting the actuals under the calculations, maybe halving the size of the area used for each row. Other hand, another column has room for at least six rows and no more real estate used (that area is currently white space). It's not a feature I'm particularly interested in, just an interesting design problem.
Forgot to mention, I have a duplex printer so two pages isn't an issue - I'm still just using one sheet and a bit more ink.
