Some questions

Hi,
I like the plugin very much, but I have some kind of language problems.
Thoug the localisation is quite good, there are a few mistakes. I want to use the lms for children in a primary school, so the use of the false words could be confusing.
Is there a way that i can fix the problem by myself?
e.g. when the course is completed, there is a prompt “gekauft”. Can I change this?
I can´t find the mistake in the language file.

I´ve got a 2nd question:
I want to use H5P resources. They fit very well to my plans.
Is there a way to implement, that the students only finish the learnpress course, when they have completed the H5P item?

regards, and
(Sorry for my bad english 🙂
