@Kirill Great, I will add this to the fog-client in the next days!
For the FOG translations you wanna take a look at the files here: https://github.com/FOGProject/fogproject/tree/dev-branch/packages/web/management/languages
The master branch points to the current version (1.5.8 as of now) and for new things we work on dev-branch (as in the link above) or created feature branches. As we don’t have much changes in the language files currently I would suggest you work on what we have in dev-branch.
Best if you grab a copy of the english version and start translating on that. I know there are many lines marked as fuzzy because of changes in strings. I was hoping to clean this up at some point but never got to it so far. If you are keen you are more than welcome to clean this up first. Would be really great!
