I will have the patch ready soon, but the gist of this is in singleframe we have the ability to create a pager. This will allow that pager to be thumbnails of the images that exist in the slideshow. Included in the patch will be the ability to allow one to hover over the pager to pause it.
The obvious question is "Isn't this what thumbnailhover is?". And this may be true. But since this is limited to images that are in the view I'm not sure if thumbnailhover offered more. Like images and the text. Did people use it for more than just thumbnail images?
