I have been using OF since its Kinkless days. But one feature from The Hit List that I'd love to see in OF is how it plays a sound when a task is marked complete. It's amazing how motivating it is to me. I bet that this behavior could be mimicked in OF with a simple script triggered by a key press, but I don't have the know-how myself. Is there anyone who'd be interested in jiggering something up to do this?
