A close cousin 😉

Maui confuses me. The Plasma Mobile homepage features Index, Pix and Vvave prominently. Additionally, those three and Nota are featured on apps.kde.org and the git repositories for all Maui applications are hosted on KDE's GitLab at https://invent.kde.org/maui. Index in particular is very important for KDE, since it's the only mobile-friendly file manager Plasma Mobile has. The Maui blog is also aggregated on Planet KDE. So clearly Maui is very closely related to KDE.

However, Maui Shell is hosted on Nitrux's GitHub, not KDE. Maui apps also don't use a lot of standard KDE infrastructure like bugs.kde.org. Plus, the elephant in the room, Maui apps have a totally different HIG from the rest of KDE. Mauikit apps are convergent, use CSD and force the standard Maui theme. They always use hamburger menus over menubars and rarely use more than one window. Apps focus on simple interfaces and simple feature sets. Some of these things, such as convergence, preference for hamburger menus and single window interfaces are also found in some Kirigami applications, but in Maui it's universal. It feels like a Qt version of GNOME much more than it feels KDE. Combine Maui Shell with Maui applications and you end up with a desktop environment which has nothing in common with KDE's flagship Plasma. So what's Maui? How is it related to KDE? I don't get it.
