I would rather have a traditional bank reconciliation report where it lists the unreconciled receipts and payments. You have copied the Sage "Statement Report" method and its pointless.
Balance per Bank Statement
Add: Unreconciled Receipts (listed somewhere on the report)
Less: Unreconciled Payments (again listed somewhere)
Balance per Kashflow TB.
I'm not interested in the items I have reconciled - I just ticked them off. I want to see the items I didn't reconcile. This type of bank reconciliation will also be a lot smaller to print.
Add insult to injury, the Unreconciled Items report is just awful. Date takes up 2/3 of screen and comment/detail get a tiny column, you have to use the browser print as it does not have a button and you can't even export. It also does not distinguish between separate bank accounts.
