I love this plugin. It solved so many problems for me - thank you!
Just a piece of feedback. It was driving me crazy that I could only see previous posts until I finally found the small "screen options" link in the top right (I use very few plugins). I'm surprised I actually found that...it looks like part of the WordPress Admin header, not part of the plugin itself. More options are always better, and "Relatedness Options" and "The Pool" could just be shown by default.
Also I'd have "Show only previous posts?" unchecked by default.
