Other information that you think might be useful:

Why combining effects is not allowed? It could make this mod extremely more versatile, in my opinion... Think of it this way. I want to prepare for battle, now, I already have stacked vials, nice. I also have alchemy bags filled to the brim with them, NOICE! But I have at least three different alchemy bags on me at any time, :/. I understand it could get really OP really quickly, but by combining effects the duration is decrased a 20% (or any other value) per effect added. Also, you would need something more powerful than a slime ball to combine them this way... oh I know! why don't we use magma cream! The heat from the blazing content concentrates the mixture and blends the properties irreversibly, at a cost.

Also, splitting potions using water bottles (or water splash potions/lingering and create a vial filled with water) instead of empty bottles makes sense doesn't it? Sort of like diluting the content of the potion into water vial/splash/lingering/regular that are crafted with the original.

Why don't also include empty recipes for splash and lingering potions in the brewing station? (Empty bottle + gunpowder = empty splash bottle, throwable the same way as a regular splash, just nothing happens.) This way you could craft a potion with this empty ones to transfer the mixture safely the same way you do with the vials, just more flexibly and reversibly.

I'd rather keep the mod simple, honestly, most of the stuff you suggested would require a lot of infrastructure, I feel like it goes beyond the scope of this mod
