@prytolukster has noted that life would become very struggling, if Gnome Nautilus and Gnome Shell Extension such as Desktop Icons will not support ability to simply dragging and dropping files between them.

• General support of Drag and Drop between Gnome Nautilus and Desktop Icons
• Support for keyboard shortcuts
  • Copy and Paste (Example: Microsoft Windows: CTRL + C and CTRL + V)
  • Move/Cut (Example: Microsoft Windows: CTRL + X and then CTRL + V)
