 * group by hostname or group env var in registrar
-* daemonize registrar and tide executables
 * Ctrl+D should not pass tag name as arg when executing tag commands
 * 'Get' tag with argument currently segfaults
 * registrar doesnt match open windows when new file created and is then opened for edit or line number
