Drag & Drop _within LimeWire_ was removed, as was renaming files, because it was way too problematic. The DnD stuff was homemade and was causing lots of problems, and lots of people were renaming things without meaning to. We weren't able to come up with a feasible solution in time, so the best all around solution was to remove on.

On the plus side, native DnD was added. You can drag files from downloads, the library, of the playlist out to the desktop or a folder or your favorite media app.
