Currently there are too many things you can do using Alchemy and the majority of them are extremely crucial (for producing unique resource) or highly useful (for pushing research requirement).
Compared to harvest, concept, and crafting which only have 1 or 2 primary crafting types (I considered concept as a single types because non-crucial importance), alchemy have 4 with extreme to high importance.
I proposed to split them into two which are transmute/refinement tab and brewing/refinement tab, name is of course up to dev.
