Multilingual UI / Interface Localization Support

[Igrom4ik]

LLPlayer is an incredible tool that removes language barriers and helps users watch content in different languages.
It would be amazing if the application UI itself could support translations into other languages.

Proposal:
Implement a localization system for UI strings.

Use external files (e.g., .json, .po, .ini) for storing translated texts.

Allow the community to contribute translations for their native languages.

Why this matters:
Improves accessibility for global users.

Helps language learners feel more comfortable navigating the app.

Encourages adoption in education, older user groups, and non-English-speaking communities.

I'd be happy to help with Russian (or other) translations if localization support is added.

I'm not considering globalization at this time.
The implementation cost is so high and I cannot judge whether the translation is correct or not.
