Drag and drop between windows in tiling i.e. minimalist WMs? Do any any minimal WMs, like scrotwm or xmonad (OR any others), support drag and drop _between_ windows out of the box? If so which? If not, is there a way to enable such functionality? A classic example would be to have a file manager in one window, from which you drag a file into an open application in another window to open it, etc. etc.

In X11, drag and drop is something that the _application_ must support, it has nothing to do with the window manager. For example: you cannot drag'n'drop anything in a `xcalc` window, even with the Compiz window manager.

The X11 drag and drop protocol is called XDND: see < for more information.
