Privately work on a new theme with this WordPress plugin

Have you discovered a new WordPress theme you would like to use on your site, but want to work on it privately until it’s ready for the world?  With this Theme Test Drive plugin, you can start working on a new theme using your current WordPress install, while your current theme is still showing to the public.  Only administrators on your WordPress site can view and/or edit the new theme under construction.  This eliminates the need to develop a new theme in a different install location and move the theme files and database over later, saving you much time and energy!
