I would tend to agree with the gentleman that commented on versions. version 1.0 is over written by version 1.1 - accordingly, both versions are exactly the same ..... unless I am missing something.
I often will use the same base recipe and make minor adjustments, than document my actual brew results under notes. While one could argue, these are two different recipes, I might only make small adjustments and flip back and forth between the two in future brews. It would be great to have a running file under the 'master recipe' (Version 1.0) without renaming /save as , etc. and creating multiple names for basically the same recipe with modifications. An archived 1.1, 1.2, 1.3 .... documenting each modification would be fantastic and helpful.
I also will take the base recipe and 'play' with hops and % grain to observe what it does to the base recipe on your profile. I might wish to save this for future, but limited intent actually brewing it - would be very helpful to achieve it as a version under the 'master recipe'(version 1.0) as version 1.1 to review results/ profile again in future.
