Amazon reviews report a total number of reviews and a percent of that total for each of the 5 star levels. This script adds a number to each of the star levels to bring back the erstwhile behavior, and puts the useful percent in parenthesis, on both the main page and the comments pages.
Please open an issue for requests or to report any undesired behavior.
8/7/15: Bug fix: If total reports was 1000 or more, the star-level numbers showed as NaN (Not a Number). This was due to the thousands separator, e.g. 1,234. This is fixed.
Script works under an assumption that thousands separators are commas as toLocalString() might not be supported everywhere.
Added support for single review pages that show a star table off to the side.
Added a version number. This one is now 1.3.
Version 1.4 (lost notes :( )
9/17/15 Version 1.5: Added support for .amazon.com/dp/
11/30/15 Version 1.5.1 Added support for .amazon.com/product-reviews/ (/product-reviews/ was already there.)
6/14/16 Version 1.6.1 Duplicated urls as https. While at it, reordered the @includes by length.
4/13/17 Version 1.7
