If you have 3-4 sliders active in a slideshow, it takes a lot of needlework to ensure that all sliders get equal attention. This could be solved by implementing the ability to display the active sliders in the slideshow in random order. That way, all sliders in the slideshow will have an equal probability of appearing as the first slide.

Perhaps it could be expanded so that on the individual slide you could choose to always show it first or last when a random view is selected. If there are multiple slides in the slideshow that have this option, the sort order is used to determine the order of these.
