No disrespect to the author, the plugin does work, but it seems to have a very specific purpose. If you're looking for a scroller using post thumbnail images, this would be perfect. But it really seems to be designed around the thumbnail being the focus and that's not what I needed.
Also, it's horizontal only, so again seems very specific and not configurable. Considering the last two scrollers I tested didn't even work, I give the author credit for providing a functioning plugin.
On word of advice to the author: it would be nice to see a screenshot of the plugin in use so we can know what to expect.
