Where can I find the original lines for translating the firmware from English to other languages?
Developers, are you planning to move the translation project to a more convenient platform for this, for example on crowdin.com
Why are these files not in the English repository?
Are these some old files or are they untranslatable?
It's just strange that there are differences in files in different localizations.
According to your Slovak translation repo (and translation guide) you have main folder with typical strings and additional folders with files that have extra strings per devices. I don't see such structure of files in Compare repo. There are separate folders for devices and no "main" folder. As I understand you are using some standalone software to compare/combine/split strings. I tried to find information about it in the manual and on the forum, but to no avail. Can you help me with this, probably I'm missing something?
