It would save a ton of time, help prevent mistakes and provide a better user experience if the report filters loaded by default were based on the last settings used.
Example: Yesterday I helped a client reconcile some payable charges. We had to go back and forth between the a/p charge rec. report and the GL report to basically identify which payments went against the wrong invoices. We had to change the accounting method from cash to accrual each time, which after a while felt tedious, and if we did not pay attention it would have also had an impact on the adjustments we had to make later. Furthermore, the customer in this example wanted their balances as of the 1st of the calendar year even though their fiscal year ran from july 1st to end of june, ands after going back and forth several times and having to repick the date each time I could send the user starting to get frustrated.
