Synchronizing without gpodder

Gpodder handles individual “events” whenever something happens in the app (eg Play x, delete y). So that should work fine with them.

Something like that is being discussed here: Store list of subscriptions (possibly settings) through Google's Auto Backup for Apps · Issue #1899 · AntennaPod/AntennaPod · GitHub I do not think yet another setting for that would be good, though. So I would only do a pre-determined interval.
