Well, my first native app just landed on Openstore. https://open-store.io/app/ttbn.lduboeuf
I've only used QQC2 components and imported needed svg icons from suru theme.
I admit that as a QML beginner, it was sometimes hard to make things work and displayed correctly... color theme is still not that good.
But i'm happy that i can now build for multi os and still use QtCreator.
Thanks for all your examples
