Some suggestions
Useful things
I'm just posting these here so I don't forget about them. If any of the devs want to make these then go ahead, else I will add them when I have some time:
productionScreen.close()
If production screen is open but you decide not to make anything (no items left etc.).
ATPA.deleteIndex(const index : integer)
Useful for removing TPAs from the array
MM_SYMBOL_EVENT
Symbol by the well south of GE (this is a permanent symbol)
