colorSelectorInput feature request: order of colors

[pepijn-devries]

colorSelectorInput, as far as I can tell is the only Shiny Widget that allows the user to select a vector of colors, which is fantastic. Currently, the order of the selected colors is fixed and needs to be predefined in the user interface. It would be nice if the user could modify and control the order of the colors (perhaps by drag-and-drop). Could the widget be modified to support this, are there alternative widgets that support this, or are the work-arounds for this?

Thanks for the great work!
