When I generate a balance report for a group of accounts, selecting the accounts is a pain because I have dozens and dozens of closed accounts in the account select list. I can exclude Separate accounts, but since I want recent activity (4-5 years) in my transaction reports, I cannot flag all these closed accounts as separate. They are closed, and their balances are necessarily zero, and so they don't apply to a balance report, but it's a pain to have to sift through them to select the accounts I do want.
A check box to show or exclude Closed accounts, like you have for Separate accounts, would be a great improvement for me.
