A long while back I think when 7 was introduced and there were so many new and cool things you could do. I remember people experimenting with doing drag and drop. And maybe it was more around the time script triggers were introduced.
But it would be nice to be able to drag an object and have some sort of action related to it. Maybe define the orgin and destination by context or something like that. Or maybe the origin and destination is determined by where you first click and where you let go.
Imagine being able to drag a list of sessions that you want to attend at a confernce into a portal of my sessions and have them automatically created. And likewise if you were to drag them out maybe they could automatically be remove.
On FM Go I think maybe swipe to delete - ... for portal records or list view records.
