We will soon be focused on improving the localization support offered by Plato. Whilst localization has been built into Plato from the start currently, we only offer English resource files and whilst we do have some documentation this is not enough.
We don’t have any firm timeframe just yet but we do intend to improve localization. This includes providing language packs in other languages, providing localization tooling via the Plato dashboard and improving RTL support within themes. If you have any specific localization requirements of course please post a comment here.
