// - Allow individual slides to have "selfclose"- and "individual"-flags set through
// e.g. "mode" in {slide=first css=style1 mode=IS}... where I=individual flag and S=selfclose flag.
//
// - Allow for individual speed ratings as the length of content affect the slide effect! (alt. force longer to run quicker!)
//
// - Maybe add movement with different speed at different times following a more natural pattern.
