Firstly thanks a always for effort you put into your plugins, it really shows!
Regarding the Rating plugins I would like to suggest the follow as it's lacking in many other ratings plugins out there and I think it would push this plugin to the top of the line.
1) Schema, a full spectrum of schemas. Article, review, place etc. So many plugins out there don't give a full listing, and secondly it's what's needed to boost this plugin up a little ;)
2) sort by most voted. I know it's there somewhere! But it's quite hard to simply get a list of one's most voted for articles or reviews. At the moment one just gets a long list of "Title, then rating" I'd like to see it sorts as "title then - how many 5 stars, 4 stars, 3 stars etc" it got.
3) changelog. There's a lot of updating these days, I don't see any updated changelog here. Even if you keep the change log elsewhere it would be great to have a link saying so. I downloaded the latest but even the .txt was hard to read and figure out what had changed.
Again, just my 2cents.
