Downloads used to be shown in a completely separate window, which
could be toggled using the keyboard shortcut Cmd-Option-L. In

Using FastScripts and a simple UI Scripting script, I was able to
restore this functionality, so that Safari on Lion toggles the
appearance using the old familiar Cmd-Opt-L shortcut.
