It passed QA and is now available as Vimeo Listing
The funny thing is that it was made on a rainy weekend in January. After I had sent it for validation it took more than a month till I got the first feedback from the Joomla! QA team. Then I fixed the reported errors. A week later my extension was simply disappeared without any feedback. So I uploaded it again and another two month later they managed to take a look at it and approve.
How magnificent! I’m done with Joomla. Big time.
