Ltt.rs
Proof of concept e-mail (JMAP) client (pronounced \"Letters\"). Makes heavy use of Android Jetpack to be more maintainable than some of the other Android e-mail clients. Features, and design considerations: * Heavily cached, but not fully offline capable. Ltt.rs makes use of JMAP’s great caching capabilities. However, marking a thread as read does a round-trip to the server to update things such as read count. The action itself won’t get lost even if performed offline. * Account setup and done. Settings invite feature creep and its friend unmaintainability. There is one specific work flow. K-9 Mail or FairEmail is more suitable for others. * Minimal dependencies. Only widely known, highly tested libraries from reputable vendors. Third-party libraries are often of poor quality, and end up unmaintained. * First class Autocrypt. Ltt.rs fits right into its strict UX guidelines. * Based on jmap-mua, a headless e-mail client, or a library that handles everything an e-mail client would, aside from data storage and UI. There is also lttrs-cli, which uses the same library. * Looks to Gmail for inspiration in cases of uncertainty.
