That's a fantastic plugin, exactly what I was searching for.
First thing noticed : it's "english only".
I've got no problem about that because I understand english quite well myself but I'm afraid that my visitors (most of them are French) won't be so happy about that.
I managed to translate and update the strings manually "inside the code" but I will have to do it again after the release/installation of new versions :/
Do you plan to release a "localizable" version?
