I just want to point out that there are different levels of "nagging." I certainly don't want OF popping up alarms and stuff regularly. However, suppose, if OF is running, it showed a badge on its icon in the dock that showed the number of due-today and past-due actions, similar to the way Mail shows the number of unread messages in the inbox? That would be a simple way to prod people like the OP to check OF on a regular basis.
