Balance update

Great app! But after a period of time, the record in the app can be a little bit different with the money I actually have. The error is inevitable. (Sometimes I spent a small sum of money and forget to add it to the app or some this kind of mistakes)

If we can edit every account in the app, and change the amount of money in them that will be very nice. After very update, a deal called "balance update" can be add to the record to balance the number.
