This looks great.
One thing that my customers ask for is the ability to display rated posts in a sidebar - using a widget perhaps.
The widget would let the admin set the number of posts to display alongside the post name.
Also, the widget would display either star icons or text
The post name would be abbreviated for readability with narrow sidebars or long post names.
e.g.,
Movie review: 4/5
Another movie ... : 3/5
Thanks for listening.
