You can already translate text in plugin parameters but currently it's still a beta feature because each plugin work differently. It's not exactly translate the actual text in plugin parameter but more like make other plugins automatically display the translated text.
The manual method tho will work for all plugins, that is you gotta open the plugins you want to translate then wrap any text section with Hendrix_Localization(text). This requires a little bit of coding knowledge. If you're stuck and your plugins aren't obfuscated then you can send them via my Discord and I'll do that for you.
