    • custom function aliases and arguments (customfn.lst file)
    • comparison instructions will use condition codes, other instructions flags (eg: "cmp eax, 0" / "je ADDR", but "test eax, eax" / "jz ADDR")
    • made the "Referenced by" output an option, instead just using delineators to indicate calls ("========") and jumps/constants ("--------"), also indicating how many forward/backward references (eg: "=1<=2>==" means this function is called once before this address and twice after)
