I love the Coda Slider plugin for jQuery. I’ve used it recently to build a couple of tabbed “widgets”. One here on CSS-Tricks in the sidebar to show Script & Style links, Featured Posts, and Popular Posts. Just kind of a fun way to show lots of content in a small area. I also used it on an article for NETTUTS for a similar purpose.
Both of these examples use the Coda Slider pretty much “out of the box”. Sure the design was heavily altered to fit the job, but the actual functionality wasn’t altered in any way. I recently had the calling to build a “featured content area”. The Coda Slider fit the bill almost perfectly, but it needed a little functionality surgery to do what I wanted it to do. Special thanks to Benjamin Sterling for helping me out and figuring out some quirks for me.
