Kazv
Kazv is a client, which is currently in beta, that is aiming to have the least bloat possible, it currently supports E2ee (End to end encryption) and Multi language.
Kazv has said that features like spaces or room discovery are not necessary, and that many [Matrix projects do not prioritise features for private conversation.
This client is prioritizing simple UI and customizability, they developed a shortcut library which allows users to customize shortcuts for various actions
