Interesting about this because my in-house localization plugin isn’t compatible with the project I’m working on (Have an issue with MZ3D). So, can I translate commands like New Game, Save, etc.?

Also, can I check the 'Used Language' using a script in a conditional branch? I want to use it for some purposes as well."

Hello!
Yes, you can translate everything from your game using this plugin. You can also check the current language using a conditional branch. It also has a feature to use a localized version of picture without the need to use any conditional branch,  meaning you can leave the Show Picture command as is. Magical, right? ✨👀
