@agx Nice! That's a feature I wanted for apps to test a11y and themes and to keep their AppStream screenshots up-to-date. :)
@KekunPlazas Wonder if we can repurpose this. I currently do this in process so i can peek at phosh internals but running a separate app looks doable too. Getting the locales into place could be fiddly but maybe we can grab the flatpak artifact and run and screenshot that under different locales?
