Question: allowing metacity/mutter/compiz/other to raise target window while d’n’ding will infringe some Apple Inc. legal stuff?? 😀
If not, couldn’t it be a cooool addition for 3.0? Let’s imagine: you start the drag action, dwell on (partially hidden) target, the window manager raise the target, you can drop anywhere in the target.
PS tip of the day for new GNOMErs: you can do something like this using the window list (aka taskbar) as intermediate target.
