I like it, but it could improve.

I really like having so many shortcodes quick at hand. The only thing I would suggest is to have some better examples in the popup dialog box that opens when you click a shortcode topic.

You have a link that opens a webpage, but it doesn’t show what some of the shortcodes actually do…

The columns one, for instance, was a little confusing at first. I figured it out with the help of Google, but was disappointed that the plugin didn’t offer that information for me.
