Use a different Front End

Hello, I own a Raspberry pi 3 equipped with a TV tuner and I’ve installed LibreELEC / TVHeadend (backend) on it.

Unfortunately TVHeadend’s client (front end) does not support the Greek Language (causes boot loop). I’d very much like to help in the translation process but since I’m lacking the time for the time being could you advice me which Front End (if anything) I can use alternatively?
That is to say, is there a front end which can read the data from TVHeadend’s backend?

If that’s impossible, the alternative is to keep the client add-on in English while the rest of the System in on another language.
Can I selectively choose the add-on’s language?

Thanks for your attention and support.
