Bazaar is a modern Flatpak app store (not only) for GNOME. It is the default, pre-installed app store on Bazzite and some other popular distributions. Recently, Alza, the largest Czech chain of computer and electronics stores, which also operates in Slovakia, started selling gaming computers with Bazzite pre-installed.
Unfortunately, Bazaar is still not translated into Slovak. If you have the capacity to do so, please consider translating it. You can use our Czech translation as an example.
