Be able to drag and drop files between Library's on SharePoint online.
If you use meta data, and not folders in document libraries it is virtually impossible to move files from one library to another because you can’t drag and drop files from a grouped view. If you go to Windows Explorer View you can’t find files because they are arranged with meta data in Libraries. The ONLY way to do this is to individually download locally and then upload to different Library. Ridiculous and very time consuming.
