A new running total column has been added to the bank reconciliation screen.
This makes it a lot easier to find any errors when comparing the transactions with a bank statement. You can go down the list of transactions looking at the running total compared with the same transactions and the same running total on your bank statement and find the exact location where the running total varies.
Note that the running total is in date order. If you change the sort order of the transactions in the list the running total will still be based on the original date order of the transactions.
