I really liked the interface of the plugin demo. It only took me a few seconds to get the gist of it. I like the eye icon for switching from "show" to "hide", and that you can differentiate between "index" and "posts" when defining category display.

It did take me a while to realize I needed to start typing "category" to get a list of the categories, although that probably wouldn't have been an issue on my own site, because I would have first tried typing the name of one of my categories. Also I'm still unclear what Option 1 and Option 2 are. (I'm fairly new to WordPress, so forgive me if that should be obvious!).
