What?

Maybe I don’t understand what this plugin is supposed to do, but I had no luck. It displayed nothing.
I wanted to add related posts at the bottom of a page using a widget. The widget had exactly one setting, a box for entering the title. Nothing else. How to select or filter the posts to display?
There was a Settings menu for this plugin, but it contained no easy way to select post categories or tags either. And even if it did, wouldn’t that mean that every instance of this widget would display the exact same posts?
