Work with multiple desktops is a Windows 10 great functionality, however, it seems not to have a keyboard shortcut to easily move a window from a desktop to another.
I wonder if DF has something similar?

I don't know if this is useful but I currently use a little freeware called virtual-desktop-enhancer https://github.com/sdias/win-10-virtual-desktop-enhancer for that purpose (the development of which has been stopped by his creator). It has a lot of very useful features and I wonder if some of them couldn't make their way into DisplayFusion (I am a huge fan of virtual desktops being both a linux and windows user).
