Not bad

Not bad. A few small changes would make this a killer plugin:

1. You have to click the Generate button to see the latest stats – why? This stumped me for a while and is unintuitive. If updating the stats every page load is too costly for performance, it could update on a timer/cron.
2. Simplify the plugin options. Some options are quite confusing. Many people will choose to customise with CSS… so all the colour, font and spacing fields can be optional. Theming should be more like Gravity Forms.
3. Allow the Helpful item in the editor sidebar to be hidden. We insert Helpful via a shortcode in the template, so the sidebar does nothing.

Despite these grievances I’m very grateful for the hard work that goes into making and supporting a plugin. Thanks for your efforts!
