The brewing stand, arguably the game's most opaque interface, becomes a real visible process.
The vision
The brewing stand is arguably the most opaque interface in vanilla: three bottles, one ingredient, a bar going down, and no way to understand what is happening. It is exactly the kind of station a general-purpose module can only handle on the surface.
A dedicated module would allow the depth alchemy deserves. Today, brewing stays in Tactile:Blocks and nothing is being taken out of it: what follows is a track, not an announcement.
The gesture would replace the screen from end to end: grinding the ingredients, dropping them into a boiling cauldron, watching the color turn and the mixture evolve before your eyes. Everything is read in the liquid, with no interface at all.
The cauldron's heat would reuse the forge's infrastructure rather than duplicate it: a single technical brick serving two modules.
Rather than a fixed list of pairings, a mixture's effects could be derived procedurally from its ingredients and its handling, temperature and duration. Experimentation would then become the module's core, not a table to look up elsewhere.
The components themselves would be alive: Biome's flora and Season's cycle would condition their availability and potency, tying alchemy to the ecosystem instead of isolating it from it.
