* ~~[Autocrypt Setup Message](https://autocrypt.org/autocrypt-spec-1.0.0.pdf) (section 4.4)~~ (IMO it is not a good idea to let an email client handle sensitive encryption keys for an exceptional use case while OpenKeychain can export keys too)
* ~~Generic unified folders~~
* ~~New message notification schedules per account~~ (implemented by added a time condition to rules, so messages can be snoozed in selected periods)
* Copy accounts and identities
Anything on this list is in random order and *might* be added in the near future.
