We recently started to take better care of translating our applications in our native language as well as English.
This way our clients will have a more professional experience.
Even if we have everything translated, the preview that we see is in the language used for naming the steps/paths initially.
It would be a nice touch if the language of the preview would be the same as the language selected in the users settings.
Obviously, if a path/step has missing translations, the default value would be used.
