Is there any reason you have opened and closed this PR a couple of times?

Yes, that, and also made some improvements, but don't know how to edit an already-made PR...

Okay, no problem 😊 Don't worry, if you make any changes in your fork's branch they are automatically included in the PR.

Oh, and thanks for the PR!

We'll wait until we have a review, I'm discussing with someone to check the translations. Thanks for being patient here.

I think I never saw a ru-RF code before, it's always ru-RU. 🤔 I think we should change that before merging the initial support.
