This little module just lets you define your marquee view, your draggable view for sorting the marquee, marquee content type, and the number of slides. It will then create contextual menu items for your marquee: Sort Marquee Slides, and Add Slide. The js included also fades the draggable view rows that won't be used and adds a dashed line to clearly mark which slides will be included.
For a more robust solution, keep an eye out for my Contextual Links module
