I use Tab Mix Plus mainly for Duplicate Tab. That function is absolutely indispensable to me.

TMP is one of my favorites. Still things about it I didn't know. Sorry, I forgot to mention that Muse. It merges every window into one single window. I am not aware of any functionality that will allow you to merge with just a specific window. Don't get me wrong, this might be possible. I just don't know of settings.
