I see no reason reconciliation cannot utilize the already existing code used for walking users through finding duplicates in QIF imports. Reconciliation is all about finding duplicates in order to identify lone transactions.

Having gnucash import a QIF, identify likely matches, then prompt the user whether to mark Reconciled is far faster and more efficient than the current system of my printing out my bank statement and manually checking off each transaction on paper switching back and forth to the gnucash reconciliation screen to click on the matching transaction.

And the code is already there!
