We've been doing some big calculator updates for ATF.

Formulation Mixes

We've added a formulation only mode to the calculator, so you can make premixes.

Premixes

You'll be able to add a Premix to the calculator, which can match the formulation or be additional ingredients. You'll also be able to replace a formulation with a premix.

Flavor Shots

You'll be able to mix with a flavor shot of a recipe.

A big focus of the calculator changes initially were to make it more modular, but I'm not very happy with how that turned out. That will happen, but it'll be a work in progress and may wind up being a separate experimental mode.

We've fixed a few bugs with the calculator, most of which people haven't seemed to have noticed. I also fixed some bugs in the Recipe History display (again, probably unnoticed). There is one outstanding bug for remixing a batch, but I haven't tracked that one down just yet. I also fixed a bug that wasn't counting mixes correctly and one that didn't update if you added a flavor to flavor stash/favorite from a recipe.

I've also worked on improving the formulation selection for mixing, including a selector in the calculator. This won't be in the next update, but it's coming.

There's more, including some enhancements for tags in item lists and some public batch improvements, and some all new stuff that has been a work in progress.
