I tried using Acrobat Pro DC for the first time recently and I was shocked to learn that some key drag & drop functionality no longer exists in Actions. Drag and drop is a must-have. Also, I cannot edit actions imported from an earlier version of Acrobat Pro. The video at the following link shows what I can do in Acrobat X and what I can no longer do in Acrobat DC. There are also some other items that are missing...

The drag-and-drop functionality is important for the tasks that I complete. Not being able to drag-and-drop files as I have shown makes theses types of tasks more difficult to accomplish and takes more time. I really want to use the newest version of Acrobat Pro. But not being able to drag-and-drop files for my automated actions and not being able to edit actions imported from a prior version of Acrobat is preventing me from using the latest version.
