Very nice! There are a lot of rotator plugins out there, but yours seems very complete and robust. I will definitely be using this in future projects since our clients always want more fancy sliders. Thanks again!
What business are your clients in? I tend to think of slideshow transitions as something users find enjoyable only for a very short time. (I run a photosharing site -- http://ourdoings.com/ -- where I recently redid the slideshow to use photoswipe, which works well on touch devices but does not do fancy transitions.)
Our clients are typically churches and small business who like to have banners on their home pages. There's always something "featured" that they want to show off.
That use case makes sense to me -- a quick attention-getter.
