I had two problems. The file I downloaded was not complete, the plugin part was missing. Also there is a small bug in the plugin.
Support works fine. I received the missing plugin within 24 hours.
I also did a translation into Dutch, which was not too difficult. It does not support language files in its current version.I think for the creator it's worth developing it a bit further. Altogether, I'm happy. It solved my problem.
Wow, 3 stars for a free extension that does what it says, is easy to install and configure! What documentation is needed to change the style via css?
