The extension is excellent, with lots of things to configure. Installed a different extension of this kind and it did not work plus messed up my layout badly. This one worked out of the box but needed to be tweaked a little to do what I needed it to do. I was overwhelmed with the loads of options at first and had to drop a few lines to the developer. He responded promptly and professionally (and this is a free extension, mind you) so I was able to finally make the jbetolo work the way I wanted it to. Yay! I wish there were more extensions and developers like this. Thanks!
