@Tut thanks for the clarification. As you say the choice is mine. I will continue to use the bank account features for a credit card, mostly for the reconciliation functionality (cleared/uncleared) as that is more useful for me now than a clash flow statement that records credit card purchases in the month they are paid rather than the month they are spent.
@lubos if you have any plans for providing this functionality in the near future (liabilities with reconciliation perhaps) , let us know.
