I was happy to find out that Appigo Todo can put items in the notification center. However, is it limited to 15? I went to Settings | Notifications | Todo | Show in Notification Center and bumped it from 5 to 10, and then even restarted the phone, but it seems stuck at 5. (Honestly I'd like to see EVERY due item (15 for me currently...) but 10 is a good start)
I see an update but it looks like you guys missed this one.
