I use a lot of different plugins and nothing is more frustrating than installing something with such promise and then having it literally not show up on a simple site. The widget does not display when it is installed. I cannot find the shortcode anywhere, which would take 5 minutes to layout in an example on a support page. And I see many support requests here that are 2 weeks to 3 weeks old and not resolved. Not the sign of a plugin that could be used with any efficacy.
