Quicken
Several years ago, Quicken chopped off the usability of the QIF file format for importing data from accounts to gin up their new interface process, which, if I understand correctly, was more expensive for banks to impliment (or so claims my credit union). In the interim, I switched to the Evile Empire's Money, until the Evile Empire dumped the product line. Today, I figured out I could import QIF files into cash accounts and then move the transactions to other accounts. D'oh.
