* Single window mode does not work (the XWINDOWID hack does not work in Apples X11 server, so this may never get fixed).
* It is possible to use GTK to build native OS X menus: http://developer.gnome.org/gtk3/3.4/GtkApplication.html . It would be awesome to do this and hide the main GTK window if the top bar is available
* Be sure to include details about new scons features for package maintainers so that the manpage, luascripts, and auxlib will be included in future packages
