Plugin is working great on front end, but its strange, that Setting in dashboard is missing somehow...
It's mentioned as being a todo
I've once continued to work on that plugin, but I do not remember how the status have been. I've uploaded that project to github, just now. You can try the version from there.
I would strongly suggest you first disable the version you re using right now, completely delete that folder, and then upload and enable the new version.
But I really don't remember if that newer version is better in any way...
