Such a good plugin abandoned

I’ve been using the joomla’s version for years, and I have to say it’s a wonderful extension, now I find it in wordpress, but it lacks screenshots, a demo and basically everything else, and looks like the project was abandoned by the developer. I’d be willing to pay for it if it had the same investment it has on Joomla.
