Rated 4 out of 5 stars

i think you should add these functions:
- users may upload (or specify the path to) their own arrow image and set it's css options (transparency / shadows / etc)
- close, pause, scroll to bottom buttons are optional

This review is for a previous version of the add-on (2.1.1-signed). 


Its been long time but I hope you have got few of your requested features in the latest releases.. :)

I'll give the transparency feature in the upcoming releases.
