If this had the ability to add textBrowser Info Environment
Your timing is good. I built out a site today for a client and added a testimonials panel that faded a message on top of the image slideshow. The way it worked was by adding attributes to the image files - as each new image file animates in, the add on scans it for those attributes and fades in the corresponding message. It works well, but it's set up uniquely for the site at the moment.
Give me a week or so to clean it up and I'll push out a new version.
