Rated 4 out of 5 stars

Very useful add-on, so glad this is available. Big positive that it offers etymological info, and clear distinction between US and UK spellings / usage.

(Lost point for the fact that the link breaks periodically and searches no longer work.)

This review is for a previous version of the add-on (20130428). 

Thanks Branais. I uploaded a new version last month to correct the problems you mentioned. Is this the version you are referring to, or the older one?
