XF 1.2 Transaltion of the Front-end only

OK, got me a license (first of many, if things go well) and got the language export (demo site)

there are close the 5,500 lines ... that seems a bit high ... maybe in the future ...

my question is: how do I identify the ones only seen by the users

I do not have the time to do all, but can definitely take care of the front-end language now.
