I’ve been wanting to share this comprehensive resource on drag and drop UX best practices from Smashing Magazine with you. Perhaps it will help make the new drag and drop experience in Cornerstone even better, or maybe you’ve already got it perfected. We’ll see in the beta
So, in case it may be helpful:

The Smashing Magazine newsletter is definitely worth subscribing to by the way, lots of good stuff like that in there.
