I use the cloud connection (Dropbox), so I can't use any schedules for a wireless device connection
What I would like is a shortcut or something like that so that I can trigger a cloud sync whenever I've automatically established a WiFi connection at night with my automation tool. "Cloud sync" meaning that CC would pull all books not on the device from the cloud and (maybe) delete all books that are no longer available in the cloud. Though it would probably better if an automatic sync would not delete anything or only as an advance feature with a proper warning at setup
That way I can better control the sync. So only try to sync if WiFi is connected and battery has enough juice or charger is connected or something like that without adding that ballast to CC...
