This topic is all about the Russian translation of Mp3tag for Mac.
If you'd like to help translate Mp3tag to Русский or if you spot a mistake, have suggestions, or comments, please leave your reply here.
Thank you for creating the topic. I did some translating a couple of days ago, will resume later this week.
A fair amount of menu items that are just the macOS system ones, so I will switch my system language into Russian and compare and copy the translation. I think it is important to have consistency in this case.
I also inspected the Russian translation for the Windows version of the app. It would make sense to mimic the main terminology, even though I slightly disagree with some elements.
That sounds just great! Thank you. And I think you should go your route where you disagree, in the end people will mention it if something is totally off (what I don't expect).
As a related note, you can start any application with a different locale by passing the following command-line argument to the application binary when starting via the command line:
-AppleLanguages '(ru)'
It seems like the Russian translation came to an halt. So if you're a Russian user of Mp3tag for Mac and like to help with the localization, please feel free to chime in 
Hello Florian!
First of all, I want to express my sincere gratitude for your software. I use it constantly; it is truly an excellent tool.
If you are open to it, I would like to contribute by translating Mp3tag for Mac into Russian. I would be happy to help with the localization to the best of my ability.
Thanks for the kind feedback and glad that you like Mp3tag!
It would be great if you could contribute to the Russian localisation. I just sent an invitation to join Crowdin.
Thank you! I’ve registered on Crowdin. I’ll need a bit of time to get familiar with the interface, and I’ll move forward with the translation as I have free time.
I’ve spent some time getting familiar with the interface and I already have two questions. I didn’t find the answers right away, so I thought it would be better to ask here instead of guessing.
Is it possible in Crowdin to sort the strings for translation alphabetically? And the second question: is there a way to group or filter the strings according to the Mp3tag interface sections? For example, menu bar items, File window, Edit window, and so on.
I don't think that this is possible, but you can search for, e.g, menu or more specific NSMenuItem to get all menu items.
Mp3tag for Mac is now localised to Russian as of v1.10. Many thanks to @PilgrimOV for the high-quality localisation!
