Yes i live in country when many people speak russian, but it extremely uncomfortable navigate with new transkate.
Fisrt - menu item change they position in they list.
Second - meny term sound & write difference between ang & ru.
Third - i looking for instruction how switch the language, tried to search some in code but....
Please add this in settings or instruction.

Then, i deleted all localization files except "en" variable.
All is working now.
But i think it will bу good if u add the possibility to choise lang.
How ever thank u kingly for MechJeb.

It is not possible to add a setting. If you want MJ in English you need to delete the Ru localization or switch KSP to English.
