Valuable Rated 5 out of 5 stars
I'm not an expert, so 5 stars because it works, fine and obstructively. Just made me find out I had had a nested bookmark for ages! That's for the smile (it wasn't vicious) but I am realizing at the same time the implications with nasty obfuscated links. Good find.This review is for a previous version of the add-on (1.0).
