Substitute neo chat - official KDE network client Matrix.
Neochat is a fork of the Spectral client. The user interface has been completely rewritten using the Kirigami cross-platform framework. The client supports Windows, Linux and Android systems.
Repository on GitLab (current).
Repository on GitHub (inactive).
I couldn't find actual screenshots of the new interface on Kirigami. Once development was carried out on GitHub, there are screenshots of the old Spectral client. IN list of clients he doesn't exist yet either.
