This is one of those once-in-a-lifetime discoveries. The slider is INCREDIBLY well designed, infinitely flexible, and unbelievably robust.
It does involve a learning curve to get it to perform some of its tricks, but the quality of support is fantastic - not simply refering you to a list of FAQs as so many plugins do, but with real people who guide you to the effect that you are looking for. Furthermore, they have done this on one occasion at 5:30am.
I've tried to avoid expletives, but for those who prefer them - Awesome and Rocks!
Thanks guys, keep up the great work.
