Batches on All the Flavors are the result of mixing a recipe. They are an optional last step (Create Batch button), but they are useful snapshots of a recipe's history, and they provide the utility of updating Stash amounts. One of my goals is to make the batches more important and have more utility. The first step in that was to allow batches to be public, which has partially been done, but there isn't a public directory of batches, you have to have a link to find it. Now I am working on allowing you to remix a batch. I'm still working out the exact details, but the goal is to allow you to just go to a batch, click Remix, and do it over again. It's currently functional, but it's not using all of the batch data explicitly, as I'm still working out option for formulations.

This is a pretty big change in the normal workflow and isn't even the end goal. I wont share all of the plans, just yet, but this new feature, combined with public batches, means you can easily share different iterations of a recipe and other users can actually mix them. It also allows you to move recipe development out of the main recipe, because you can edit in the calculator and keep remixing, editing, etc before updating a recipe or needing to make copies of a recipe. It keeps the workflow for a recipe contained to that recipe, without requiring changes that you don't know if you want to keep or not. It also means if you've mixed a recipe and it was later changed, you can still mix the original recipe without cloning it, just remix the batch you mixed before.
