You cannot drag files onto it to open in other programs or copy/move them, last I checked. This is a showstopper for my workflow. I just want to drag a file over my explorer icon, choose the window from the popup preview that I want to move it to, have the window get focus, and drop it in the window to move it. Or drag a file over a program icon, have the program get focus, and drop the file on it to open it. Apparently, that is too difficult to port from every previous version of Windows into v11. It sucks.
