Yes - I understand that. I probably use Beersmith differently than most people.
I have a PC in my garage, in my home, and a phone and a tablet. I tweak recipes on all of them. Sometimes I will make a minor change that adjusts something else. I usually catch it, but not always. It's more of an inconvenience than a problem and it's entirely my fault.
As far a features, I like having the timer and all the conversion tools in one place.
I'd love to see a more robust database for ingredients that I could easily refresh as needed. The current one is fine, but I'm not super comfortable adding my own ingredients to the DB. I'd rather be able to pull from somewhere that I know has been properly vetted by someone who knows what they are doing. I'd even be willing to pay for that if it was available.
