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.
