eMap Switcher Widget - change the order of basemaps?

Hi,

I have a "deferential" idea how to improve Robert´s eMap Switcher widget (it would be very useful with ability to fade), but it seems I´m not able to make it work, so I´m starting a discussion here...

Is there any chance to add tool to enable users to change the order of basemaps? Tool like "move up/move down" which is possible with operational layers.... It would be very useful, many users would be very grateful!

Robert, what do you think about this idea? Should it be possible to add this tool into your widget?
And of course - many thanks for your excelent work for "the community"!!!
