I used it about a year ago and it was pretty useful in making some large decisions but the more I used it, the harder it became to use as I couldn't duplicate and mutate easily without breaking my prior work, or basically without a version control system. I'm probably at a point where I would look at it again but today I would like it if actually worked with my day to day transactions as well, reconciling with all my checking accounts. Also multi-currency support would be very useful.
