I come back and try to use this plugin from time to time, but usually end up disabling it because it's confusing to use.
When you disable and then remove it, the web site breaks! How annoying is that?
Now there's a really annoying nag screen that keeps asking for reviews, links, support etc.
OK, it's a widely used plugin and developers need the support of their users - not everything in life or online is free and nor should it be, but those nag screens will be the death of the plugin, as users like me will simply not use the plugin any longer.
When the plugin works, it works well - but it's over-complicated in my opinion.
