I think your plugin is great!
We updated some plugin the other day and our site become a bit unresponsive. I deactivated everything and slowly activated our 30 something plugins to see what was conflicting. Sadly when I activated 'KK I Like It' my WordPress menu would no longer pop out when hovering over and I could not drag and drop my widget any more.
I have had to deactivate for now, but hope you can assist so we are able to active again. I think maybe the conflict was the plugin 'WP Symposium'.
