Rated 5 out of 5 stars

Alexander, I really like this extension, but I have a question. I couldn't find any way to contact you via the extension home page. Is there a way that I'm missing?

This review is for a previous version of the add-on (2.0.5). 

You can contant me in the German support forums (the forums interface support English language):
