I like it Rated 5 out of 5 stars

Thanks Wladimir for implementing this useful tool.
As a side note, I would suggest you to add "oncopy" and "onpaste" terms to this add-on description. I found this add-on via your comment on Robert Accentura's blog (http://bit.ly/wofkk3), not via AMO Search.

This review is for a previous version of the add-on (1.0.1-signed). 

I updated the description - when I uploaded it yesterday it was a bit of a rush job.
