Multipool is a good idea, but difficulty is how to determine what kind of algorithms use a higher income, which is probably not able to be resolved by the code.
i want this part done manually
i mean i decide which coin to mine and in which coin to payout
like sha256 miners mine bitcoin and scrypt miners mine litecoin
and if i want i can change these
and payout in blackcoin for both sha256 and scrypt miners
Then that's rubbish. Manual adjustion essentially guarantees to not get best profitability.
