I've actually wondered if that was a bug and just assumed it wasn't worth messing with. A feature, huh. Glad to know it's at least working, even if I don't care for it or follow the logic.That's actually my big problem with Reminders. Complete something on one device and watch reminders for it pop up on every other device regardless. It's weird, because you can read something in Messages on your Mac and the moment you do so, the notification will disappear on your phone, or vice versa. Not so with Reminders. While changes are synced, the reminders for it don't seem very smart.
Also, thanks for the rundown of pros and cons for OF and Things. I REALLY need to get a GTD, but as with every other area in my life, I get overwhelmed looking at all the options. I'm afraid of getting buried with yet another app to regularly track. Things may be the ticket. Now, if I could just make that decision...
