Of course. It would be a simulation option that could be toggled on and off like ambient heat and gravity.
Yeah, mods are actually more effective if you want a suggestion added to the game.
There's actually another game that's dead, but unfortunately it isn't open-source or whatever it is called so it'll be dying unless the dev finishes the other game?
I've been chasing a chemistry simulator for years. To no avail.
I tried coding chemistry in LUA, but having a reaction between a solid and water gives me black holes.
It would not be too difficult to change all the elements into the periodic equivalents and give them reactions.
To fix the black holes, you could try using simulation.partChangeType(i,tpt.element('elem')) when changing the type of an element, had the same problem as you and that fixed it.
