In a discussion about default fonts, I suggested that it could be nice to have a gallery of translated screenshots in the release notes for GNOME 44. I think that could be a nice way to show off how many languages we support.
I am not the marketing expert, but I think it would be nice to have screenshots of a well-populated desktop (ie not just gnome-shell, and not an empty desktop, but with some running applications, and in particular, some that have some text and will show translations.
There is currently a CI that builds, runs, and tests the Gnome OS. Someone could probably integrate taking screenshots as part of the testing process, as well as switching languages and taking more screenshots. But I am not sure who would implement this.
