I think having a mode in the Carousel includelet that faded between images rather than sliding would be quite reasonable. It's something I can add to my To Do list.

However I'm not so sure about doing something like this to the Background Begin/End includelet. One thing here is that it would just affect the background (of course) so even if the image changed periodically, the content in the foreground would not change, so it'd look strange and probably not be so very useful!

Thanks
