Here's a little preview of the state of our App Center. It's still quite in the early stages, but coming along beautifully. These are all apps/runtimes I have installed via xdg-app. Everything you see in the screenshots is real data, no fake prototypes.

I wrote much of the Qt/C++ backend code by studying the GNOME Software xdg-app plugin and appstream-glib, so many thanks to +Richard Hughes for his hard work on those projects.
