Thank you for mentioning both the bugs and feature ideas. I haven't been keeping up with changes in the HTML structure of the comments. Today's version 0.8 should resolve the duplicate trolls and missing trash cans.

So I don't lose track of the suggestions, I added some Issues to the list at https://github.com/jscher2000/De-Troll-YouTube---Hide-Unwanted-Commenters/issues (but I don't know how soon I can get to them)
