Ive been making soap for a couple of years now and use this calculator a lot. I really like it! I think it needs some tweaks, though. First, it needs to separate my recipe from the auto balanced one by using different colors, or better yet by putting the auto balanced recipe on a separate page. I was in a hurry this morning and mistakenly used the auto balanced lye amount instead of the recipe amount (I havent made soap in a while). I might not have made that error if the auto balanced recipe was separated from the actual recipe. Second, the auto balanced recipe should try to calculate using the same total amount of oils as is in the entered recipe. Auto balance is always low, so I have to adjust it up. It is an unnecessary PITA to try to adjust the recipe.
