15751,Improve string for no themes in site admin for multisite,ocean90,,"http://core.trac.wordpress.org/browser/trunk/wp-admin/includes/class-wp-themes-list-table.php#L66
If you have more themes installed but not enabled for this site, the string doesn't tell the truth, so maybe add a link to themes.php or site-themes.php?id=x. Also it's not translated.
Some examples from nacin:
''printf( !__( 'You only have one theme activated for this site right now. Visit the Network Admin to activate or install more themes.' ), network_admin_url( 'site-themes.php?id=' . $GLOBALS!['blog_id'] ), network_admin_url( 'theme-install.php' ) );''
''You only have one theme enabled for this site right now. Visit the Network Admin to enable or install more themes.''
