I have been hunting high and low for a way to multiple select entity references and to then also order selections. This project page says nothing about the drag and drop ordering capability of Multiple Selects, and I think this is an oversight. I found out about it on Lullabot: http://www.lullabot.com/articles/module-monday-multiple-selects. Please consider providing more information on the project page so that searchers like me will more easily be able to find it. The ordering feature is highly desirable and not available elsewhere, other than the overwhelmingly complex Relation module.
