EDIT: I now noticed that this issue is partially tackled in: viewtopic.php?f=7&t=748 Currently I have to open up "My Brewing -> My Water Calcs" every time I want to test out some additions. Why is that? Why cannot I use it in a past/current recipe? Because Water Chemistry in "My brew session" is very limited. It only has mineral additions. I believe most people who add minerals also add PH changing additions(acids). I would like to do all my additions in the brew sessions, instead of having to create a separate water addition calculator for every brew I make. I really do have a separate water profile calculator for every brew sessions and I leave the brew session one unused because It doesn't have all the functionality. What do you think? Thank you for your attention.
