only slider that not only handles posts, but also shortcode-generated content

This slider is just awesome!
True, it’s interface is a bit less intuitive and slightly more nerdy than most other sliders, but:

1. it’s the only slider I could find that correctly displays shortcode content inside a post. I have a calendar plugin and wanted to display in the header-slider a slide with upcoming events. All other plugins failed, this one does the job
2. you get a lot more options and control than in other more streamlined and simplified slider plugins. Invest a bit more time to get it all set up and working, and it will pay off!
