/* changelog:
v1.73: added support for customer Q&A;
v1.72: fixed 'product specifications' section;
v1.71: remove Q&A section;
v1.70: fixed bugs;
v1.69: fixed customer average rating with the new style design;
v1.68: fixed customer review section with the new style design;
v1.67: fixed issues with Opera; cleaned the code a bit;
v1.66: incorporated some blacklist items from mason2;
v1.65: remove eGift section;
v1.64: remove user highlights sections from ebook pages;
v1.63: restored support for Chrome and Opera;
v1.62: fixed some bugs;
v1.61: added support for Amazon instant video section;
v1.60: added sampling size information as represented by different font size of
the average rating, the more reviews averaged over, the bigger the font; fixed
some small bugs;
v1.58: added basic support for use in Opera browser; removed from window title
the `Amazon.com: ' part which prevents short tabs from showing any meaningful
information; corrected multiple firing behavior when iframes are present;
v1.56: added option to hide 'Kindle Edition' section (a deep green box below the
`add to cart' box) and the default is to hide;
v1.55: added capability to move the sales rank part to just below the ratings;
v1.53: added basic support for use in Google's Chrome browser; fixed review
formatting;
v1.51: fixed collapsing problems for some book pages;
v1.50: added collapsing support for box of formats (like different editions for
books); Added option to turn on the section header triangle symbol, the default
is off as the symbol sometimes adversely affect some layouts; removed the sell
to amazon box on textbook pages; removed the kindle software for different
platform box;
v1.48: added reformatting to the specific reviews page too; added a menu option
through Greasemonkey to let the user choose whether to always collapse all
sections;
v1.46: added capability of handling the 'more buying choice' box;
v1.45: added support for the new "Customers Also Bought Items By" section;
v1.44: added support for international sites;
v1.43: improved performance by removing some outdated code snippets;
v1.42: improved handling of certain product categories;
v1.40: corrected a small bug introduced in relocation of the ratings bar; small
adjustments of presentation styles;
v1.35: now the script relocates the 'rating to improve recommendation' bar to
just below the title bar, thus provides easy access to this very useful
personalization feature;
v1.25: removed 'your recent history' on product pages; removed 'buy used' and
'more buying choices' boxes on the right since they are only duplications of
information which is avaible as links just below the title; when loading a new
page, the title is scrolled to the top of the viewing port so maximum useful
information is in view;
v1.22: removed some Kindle related clutter, such as the banner and the `tell the
publisher' box;
v1.20: added capabilities of handling multiple Amazon pages/tabs with improved
logic so that when multiple Amazon pages are opened, the intuitive behavior of
the script can be expected, i.e. the script will remember the user's preference
on the last clicked page; increased font size of the rating;
v1.05: fixed a bug where the comments on reviews are hidden from view and added
some other minor improvements;
v1.00: fixed a small bug of incorrectly collapsing items in the cart view page,
and now only functions in product view pages; also, as the script has been
tested by hundreds of users and proved to be stable and working (to a certain
extent), it's high time to gave it a version bump before New Year comes!
v0.21: fixed some newly found bugs after extensive testing on all product
categories after the previous big update;
v0.20: added capability of handling 'customer also bought' and similar sections;
now remembers user's preferences of leaving some sections open; added capability
of handling sections in boxes such as the 'your recent history' section; added
simple formatting to full reviews so they are easier to read and also gray
background to make them easier on the eyes; symbols are added before section
titles to mark their collapsing status; some previously removed sections are now
just collapsed;
v0.14: fixed bugs where product titles of DVDs and the average ratings thereof
are incorrectly hidden from view
v0.13: remove the 'SoundUnwound' section on CD pages; collapse the artist store
section on CD pages.
v0.12: add a little piece of code to remove ads section like 'Web Design Classes
in Chicago' on the product page of a book about HTML and Web design.
v0.11: corrected some minor bugs caused by Amazon's inconsistency when dealing
with different product categories.
v0.10: initial release.
