Add radio buttons to review firm + filter

First of all, thank you for a great plugin!

I have two questions to the plugin author/community:

1. Is it possible to add a radio button with two options when adding a review? If you have done on your site and like to share the URL and the know how I would be very grateful.

2. I’ve added reviews to some of my pages. I’m looking for a way to let the users filter and sort the pages on the front end. I’m looking for a way to order reviewed pages by ranking.

3. Something was written by the author about a filter plugin some months ago. Any news?

With best regards,
