Great! If I can help/test let me know. A few more thoughts:

* don't hide when a subpanel is opened, even if it loses focus. This
  may make it easier to implement. pseudo code:

gboolean hide_timeout(void)
{
  if (!panel_has_focus && !open_popup)
    autohide_panel();

  return FALSE;
}

  You may have to take some special action when closing the sub panel,
  like grabbing focus on the panel.

* no need to test if the panel is on the edge. Usually is will be near
  enough and if it's not the user should simply not use autohide, which
  in fact doesn't make much sense in that situation anyway, IMO.
