A couple more things I found. For aligning the code, Wordpress requires the classes .aligncenter, .alignright, and .alignleft for aligning things in themes. It would be better to stick those in, instead of using inline sytles, when choosing how we want carousels and images aligned, since Internet Explorer doesn't work well with some of the other style options.
And a possible feature you might want to allow users to add their own css classes to your created links, in case they already have some things defined they want to keep using.
I have the box for showing Inline Documentation checked, but nothing shows anywhere on the post or page edit pages. And when I click the Documentation button on the Settings, this is all the documentation I get: Amazon Widgets Shortcodes documentation
Just so you know, I really like the plug in. It makes linking to Amazon much less complicated, allowing me to switch between the visual and html editors without worrying about messing up the Amazon coding.
