What's in the Scheduling settings section?

Scheduling has two cards. "Device & cloud sync" controls how often the app checks your Supernote (Manual = only when you ask or open the app; Auto = on a timer you set, e.g. every 5 minutes), with a "Sync now" button. "Push to task apps" controls when your tasks are handed off to connected apps (Manual or Auto on a timer), with a "Push now" button. The push timer can't be set faster than the sync timer, because a push always syncs first — if you set it lower it snaps up and flashes amber.
