I am suprised that 4 people out of 5 say it's broken on the plugin WP page. I am using it on 5 websites and it works perfectly. It's extremely handy !
Oh and 2 of the mentioned websites are multisites. In that case, you just have to not enable the plugin on the network. Instead, enable it on each site. Then it's perfect.
Thank you for this very useful plugin !
