I pay my credit cards every month. I have these monthly payments in my Scheduled transaction to pay from my checking account. After reconciling the credit card account, Quicken pops up "Make Credit Card Payment" with options to print or hand write a check.
I suggest adding an option to the pop up to open the account's Scheduled transaction if it exists. It could autofill the amount from the closing balance. The user could change the date, amount, or cancel the payment.
